Live air quality index AQI map.
Irvine, California today from filterby.com.
Check the live air quality index for Irvine, California right now.
And find out what today's AQI actually means for the air inside your home.
Most air quality tools stop at the outdoor number.
We don't.
After manufacturing millions of air filters in the U.S.
and helping homeowners across Southern California protect their indoor air
since 2013, we've learned something most people overlook.
When Irvine's AQI spikes from wildfire smoke,
i5 corridor emissions, or regional ozone buildup,
those same pollutants are pulled directly into your home through your
HVAC system.
Based on what we've seen firsthand,
a single poor air quality day can load your air filter with particulates
that would normally accumulate over weeks.
Use our live AQI map below to monitor conditions in Irvine today,
then take the one step that makes the biggest difference for your family's indoor air,
making sure the right filter is in place before outdoor pollution becomes an indoor problem.
Quick answers.

Air quality index AQI map.
Now today in Irvine, California, Irvine's live AQI is updated in real-time using data from EPA
monitoring stations and the South Coast Air Quality Management District's network of
over Gensal's 200 sensors across the region.
Check the map at the top of this page for current conditions.
What to know at a glance, AQI 0-50 green,
air is clean, safe for all outdoor activities.
AQI 51-100, yellow, moderate,
sensitive individuals should take note.
AQI 101-150, orange, unhealthy for sensitive groups.
Limit prolonged outdoor exertion.
AQI 151-plus, red and above, unhealthy for everyone.
Stay indoors and check your HVAC filter.
What most AQI maps won't tell you,
after manufacturing millions of air filters and working with Irvine homeowners since 2013,
we've learned that outdoor AQI is only half the equation.
Your HVAC system pulls outdoor pollutants directly into your home.
And on elevated AQI days, your air filter is the single most important line of defense
between what's outside and what your family breathes inside.
A MIRB 11 or MIRB 13 filter replaced on schedule
is the fastest way to turn today's AQI reading into actual indoor air protection.
Top 5 takeaways. Irvine's AQI changes fast.
Freeway emissions, Santa Anowons, and wildfire smoke can flip conditions in hours,
and your HVAC system pulls those pollutants straight indoors.
Indoor air is often worse than outdoor air.
The EPA reports indoor pollutant levels can run two to five times higher than what's outside,
even on green AQI days. Orange County earns a failing air quality grade every year.
Ozone season and wildfire smoke make this an annual pattern, not an occasional event.
Your air filter is your home's single best defense.
A MIRB 11 or MIRB 13 filter replaced on schedule captures the fine
particulates that drive unhealthy AQI readings before they circulate through your living spaces.
Don't just check the AQI, act on it, check the map, check your filter,
adjust your replacement schedule when conditions spike.
That's the difference between reading about air quality and actually breathing cleaner air at home.
What is the air quality index and why does it matter in Irvine?
The air quality index is a standardized scale from 0 to 500 that measures how clean
or polluted your outdoor air is at any given time.
The lower the number, the cleaner the air.
Readings between euro and 50 are considered good while anything above 100 starts posing
health concerns, especially for children, older adults, and anyone with respiratory conditions.
Irvine generally benefits from coastal airflow that helps keep pollution levels in check,
but the city isn't immune to poor air days.
Its location in the heart of Orange County means freeway emissions,
construction activity, and seasonal Santa Ana Wins can shift conditions quickly.
What outdoor air quality means for your indoor air?
Pauline, smoke particulates, vehicle exhaust residue, and fine dust all get pulled through your
ductwork and into the rooms where your family eats, sleeps, and spends most of their time.
After more than a decade of manufacturing air filters and working directly with homeowners,
we found that the days following an AQI spike are when indoor air quality takes its biggest hit.
Your HVAC filter is the primary line of defense, and if it's clogged or underrated for the job,
those outdoor pollutants circulate through your home unchecked.
Protecting your Irvine home.
When AQI levels rise, a higher rated filter captures smaller particles,
including the fine smoke and smog particulates,
common during Irvine's poorest air quality days.
Pairing the right filter with a regular replacement schedule keeps your system running efficiently
while trapping pollutants before they reach your living spaces.
At Filter Buy, we manufacture every filter in the US and offer over 600 sizes,
plus custom options, shipped factory direct to your door.
Whether Irvine's AQI is green today or climbing toward red,
having the right filter already in place means your indoor air stays clean without the last
minute scramble. After manufacturing millions of air filters and working with homeowners
across Southern California for over a decade, we've seen firsthand how a single high AQI day
can overwhelm an undersized or neglected filter, turning your HVAC system from a line of defense
into a way of circulating the very pollutants you're trying to avoid.
Filter Buy Air Quality Team 7 Air Quality Resources
Every Irvine homeowner should have on hand. Look, we're air obsessed. It's what we do.
But protecting your family's air isn't just about having the right filter in place,
though that's a big part of it. It starts with knowing what's actually happening outside your door.
We've pulled together the seven most useful air quality resources for Irvine residents,
organized so you can go from what's the AQI right now to here's my plan in minutes, not hours.
1. AirNow.gov Your first stop for Irvine's real-time air quality
The U.S. air quality index is the EPA's primary tool for communicating about outdoor air quality
and health using a color-coded scale where values of 50 or below represent good air quality
and values over 300 represent hazardous conditions. Think of it as the weather forecast for your
lungs. One quick look tells you whether it's a windows open kind of day or a keep everything sealed
situation. 2. South Coast AQMD Current Data, the most detailed AQI map for your Irvine neighborhood.
Their interactive map blends data from regulatory monitoring stations,
hundreds of low-cost fine particle pollution sensors, and a forecast model to generate air quality
index values at over 1,200 locations. That means you're not just seeing orange counties
average. You're seeing what's happening near your actual home. After over a decade of helping
Southern California homeowners protect their indoor air, we can tell you those neighborhood
level differences matter more than most people realize. 3. IQI Irvine See how today's AQI compares
to Irvine's bigger picture. Although Irvine's air quality has averaged good,
levels in recent years, the city does experience short-term pollution events where air quality
reaches unhealthy. Levels are worse and has consistently failed to meet the EPA's passing grade
for high ozone days since 1996. IQI Irpairs real-time data with historical trends and PM 2.5 forecasts
so you can spot the seasonal spikes, like wildfire season and summer ozone buildup before they
catch you off guard. 4. EPA AQI Basics What the colors actually mean and when to take action.
This EPA resource breaks it down clearly. The AQI is divided into six categories,
each corresponding to a different level of health concern with a specific color that makes it
easy for people to quickly determine whether air quality is reaching unhealthy levels in their
communities. We recommend that bookmarking this one, when Irvine's AQI starts climbing,
you'll want to know exactly which level means time to check your air filter versus keep the kids
inside. 5. EPA Patient Exposure Guide Extra guidance for families with allergies, asthma,
or heart conditions. If anyone in your family deals with asthma, allergies, or cardiovascular
issues, this resource goes deeper than the standard AQI chart. It focuses on health effects that
may be experienced within a few hours or days after breathing polluted air, with specific clinical
guidance tailored to sensitive groups. We've worked with enough homeowners managing respiratory
concerns to know that the general recommendations aren't always enough. This fills the gap. 6.
1st Street Irvine Forecast Plan ahead with 30-year air quality projections.
1st Street shows how air quality will change for the city of Irvine over the next 30 years as a
result of climate change. If you're a homeowner thinking about long-term investments in your HVAC
system, indoor air quality, or even your next home purchase, this kind of forward-looking data
helps you make smarter decisions today, not just reactive ones when the next wildfire season hits.
7. South Coast AQMD Mobile App Get Notified. The moment Irvine's air quality drops.
Real-time air quality values are determined using a technique developed by South Coast AQMD
scientists and published in a peer-reviewed scientific journal that is considerably more accurate
than other methods. The absence push notifications when pollution spikes in your area so you're not
caught off guard. Pair that alert with the right merbrated filter already in your HVAC system,
and you've got a one-two punch that keeps your indoor air clean, even when the outdoor air isn't
cooperating. What the data says, and what we've seen. First hand, after manufacturing millions of
air filters in the US since 2013, we've learned things about indoor air that most AQI maps won't show you.
Here are three statistics that match what we see every day.
1. Your indoor air may be up to five times worse than what's outside. American spend
approximately 90% of their time indoors, where pollutant concentrations are often two to five
times higher than typical outdoor levels. What we've seen first hand. Irvine homeowners pull out
visibly dirty filters even after weeks of good outdoor AQI readings. Dust, pet dander, cooking
particulates, and household chemical residues accumulate fast and closed environments. None of
these show up on any outdoor AQI map. Your filter is the only thing telling you the real story.
Source, U.S. EPA, indoor air quality report.
2. Every Southern California County, including Orange County, earned a failing grade.
Over 156 million Americans live in counties that received an F for ozone or particle pollution,
and every Southern California County earned an F. For high ozone days, what we've seen first hand
are Southern California order volume spikes noticeably during peak ozone and wildfire months.
Customers report filters saturating weeks ahead of schedule during the summer and fall.
That pattern has repeated every year since we started tracking it. If your filter looks dirtier
faster in August than it does in February, you're not imagining it. Source, American Long
Association, 3. When AQI crosses 100, your HVAC becomes the front line. AQI values above 100
mean air quality is unhealthy. First for sensitive groups, then for everyone as values climb higher.
What we've seen first hand, your HVAC system doesn't stop cycling when AQI spikes,
it pulls those pollutants straight into your home. We've examined filters after major smoke events
that showed 2 to 3 months of build up in under a week. A properly rated Merb filter handles
that surge, an older underrated one lets fine particulates pass right through. Source, US EPA,
air now AQI basics. Final thoughts in opinion, the number on the map is just the starting point.
Here's our honest take after more than a decade in the air filtration business and millions
of filters shipped to homes across the country. Most people are looking at air quality backwards.
They check the AQI, see green and assume everything is fine, or they see red, close the windows,
and figure they've done enough. Both reactions miss the bigger picture, and it's a gap we've
watched play out with Irvine homeowners year after year. The outdoor AQI is a useful snapshot,
but here's what it doesn't tell you. What's been quietly accumulating inside your ductwork
all week, that your HVAC system has been pulling in, particulates non-stop even on moderate days.
That the filter you installed 3 months ago may already be overwhelmed after a stretch of elevated
ozone or wildfire smoke. In our experience, the homeowners who breathe the cleanest indoor air
aren't the ones in the lowest AQI zip codes. They're the ones who treat outdoor air quality data
as a trigger to act, not just information to consume. What that looks like in practice,
they check the AQI map, then check their filter. They know they're merbrating and what it's actually
capturing, they replace on schedule, or ahead of schedule when conditions demand it. They've
connected the dots between what's happening outside and what's circulating through their home.
That connection is what we built. Filter by around. We're not just selling filters. We're trying
to change the way people think about the air inside their homes. The AQI map on this page gives
you the data. What you do with it is what actually protects your family. Next steps, protect your indoor
air. Starting today, you've checked the AQI, you know what the numbers mean, here's how to act on it.
One, check your current filter, pull it out and look at it. If it's gray, clogged, or you can't
remember when you installed it, it's time. Takes less than two minutes and tells you more about
your indoor air than any app. Two, know your merb. Rating. Your merb rating determines what your filter
actually captures. Merb 8, dust, pollen, mold spores, solid baseline for most homes. Merb 11,
ads pet dander, smog, and dust mite protection. Smart pick for Irvine's ozone prone climate.
Merb 13, captures smoke, bacteria, and virus carriers. Our recommendation for the Southern
California wildfire season and heavy traffic areas. Not sure which is right for your system.
We'll help you figure it out in a few clicks. Three, set a replacement schedule. Then adjust for
AQI spikes. Spring and winter. Typical AQI. Replace every 90 days and summer ozone season,
check monthly, replace every 60 days active wildfire periods, inspect every two weeks,
replace as needed for automate. It filters get forgotten. Our auto delivery program sends the
right filter to your door on your schedule. No subscription traps, no commitments. Just clean
filters when you need them. Five, find your size and order direct. Over 600 standard sizes plus
custom options made in the U.S. Shipped factory direct with free shipping. No middlemen,
no markups. Frequently asked questions. Questions. What is the air quality index, AQI,
and how is it measured in Irvine, California? Answer, the AQI is a zero to 500 scale developed by
the EPA that tells you how clean or polluted your air is right now. In Irvine, readings come from
EPA regulatory monitoring stations. Local sensors operated by the South Coast Air
Quality Management District. Six tracked pollutants, PM 2.5, PM 10, ozone, nitrogen dioxide,
sulfur dioxide, and carbon monoxide. The overall score reflects whichever pollutant is highest
at the time. From our experience shipping filters to Irvine homeowners, ozone, and find
particulate matter are the biggest culprits and the ones that show up most visibly on used filters
from this area. We've seen a direct correlation between what the AQI reports and what customers
pull out of their systems days later. Questions, why does Irvine's air quality change so quickly
from day to day? Answer, geography and timing. Irvine benefits from coastal breezes most days,
but several factors override that advantage fast. i5 and i405 corridor emissions create a
persistent pollution baseline. Santa Ana wines push desert dust and inland smog coastward without
warning. Wildfire smoke from fires burning hundreds of miles away can flip Irvine's AQI from
good to unhealthy in hours. We've tracked these swings through our own order data for years
when Irvine's AQI spikes suddenly replacement filter orders from those zip codes follow within days.
The rapid, unexpected shifts are the ones that catch homeowners off guard and do the most damage
to both filters and indoor air quality. Questions, what AQI level should Irvine residents start worrying
about? Answer, the EPA draws the official line at 100. But based on what we've seen across
millions of filters we'd push awareness lower. Zero to 50, green, air is clean, the routine filter
schedule is fine. 51 to 100, yellow, pollutants are present. Worth checking your filter, especially if
it's been 60 plus days. 101 to 150, orange, unhealthy for sensitive groups, your HVAC is actively
pulling in elevated pollutants. 151 plus red and above. Unhealthy for everyone, your filter is
working over time. The customers we work with who maintain the cleanest indoor air don't wait
for red or purple days. They treat yellow and orange as early warning signals, checking filters,
adjusting schedules and staying one step ahead. Questions, how does outdoor air quality in Irvine
affect the air inside my home? Answer more directly than most people realize, every time your HVAC
system cycles it draws in surrounding air and everything in it, pollen and mold spores,
smoke and smog particulates, vehicle exhaust residue, fine dust and allergens.
The EPA reports indoor pollutant concentrations can run two to five times higher than outdoor levels.
After over a decade of examining what collects on our filters, we can confirm that it tracks with
reality. We've had Southern California customers show us filters that went from white to nearly black
in three weeks during wildfire events. Filters that would normally last a full 90 days. Your air filter
is the one barrier between the AQI reading outside and the air your family breathes inside.
Questions, what is the single most effective step I can take to protect my indoor air when Irvine's
AQI is high? Answer, have the right filter already in place before the spike, not after. Here's
what we recommend, Merb11, strong choice for Irvine's ozone prone climate. Capture smog, pet dander
and dust mite debris. Merb13, our recommendation for wildfire season and heavy traffic areas,
traps, smoke, bacteria and virus carriers. Replace every 60, 90 days under normal conditions.
Check every two weeks during active wildfire, high ozone periods. Set up auto delivery,
so a fresh filter arrives on schedule, especially heading into summer and fall.
We manufacture every filter in the U.S. and carry over 600 sizes plus custom options. Factory
direct, free shipping, no middlemen. The homeowners who stay ahead of AQI events consistently report
less dust, fewer allergy symptoms and noticeably cleaner air, even during Irvine's worst pollution
months. Don't just monitor Irvine's air quality, take control of the air inside your home.
Now that you've checked today's live AQI for Irvine, take the one step that turns that number
into real protection for your family. Find your filter size at filterby.com and have the right
merbrated filter. Shipped factory direct to your door with free shipping. Because the best time
to upgrade your indoor air is before the next spike hits, not after. At the UPS store,
