Air Purifiers from Aprilaire

Whole-home air purifiers remove pollutants throughout your home

If someone in your home suffers from allergies or asthma, you already know the negative impact that polluted air can have. No matter how clean you keep your home, it's likely full of harmful particles that can exacerbate allergies and asthma—and increase the likelihood of colds and flu.

Aprilaire can help you control the purity of the air in your home with a whole-home air purifier. And unlike standard portable air purifiers, whole-home air purifiers are installed as part of your home's heating and cooling system in order to effectively remove polluted air not just in one room—but throughout your entire home.

Indoor Air Pollution is Harming Your Health

The air inside your home could be more harmful to your family than the air outside. In fact, indoor air pollution was recently named by the EPA as one of the top five risks to public health. That's because it's filled with:

A whole-home air purifier can help you trap the most damaging particles that are common in most homes.

 "Particles rated at PM 2.5 have been identified as the most significant indoor contaminant in terms of chronic health impacts in residences … Sources include combustion products, cooking, candles, outdoor air and more. PM 2.5 can be removed using MERV 10 filters and higher.”
-American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standards Committee Guidelines – June 17, 2015

These can cause health issues, such as:

"Poor indoor air quality can cause or contribute to the development of chronic respiratory diseases such as asthma and hypersensitivity pneumonitis. In addition, it can cause headaches, dry eyes, nasal congestion, nausea and fatigue. People who already have respiratory diseases are at greater risk."
- American Lung Association

A Whole-Home Air Purifier Can Help

Whole-Home Air Purifiers are installed as part of your home's central heating and cooling system, away from living areas. The air in your home runs through our state-of-the-art filter media, delivering clean air throughout your entire home, silently and efficiently.

Maintenance of our air purifiers is easy and infrequent, requiring attention just once a year. Compare that to portable air purifiers that only clean air in a single room and require cleaning every 1-3 months.

Whole-House Air Purifiers Clean the Air on Your Terms

Unlike air purifiers that only work when your heating and cooling system is running, Event-Based™ Air Cleaning from Aprilaire lets you call the shots. You control when and how the air purifier works based on day-to-day events, conditions and activities, such as:

  • Allergy season
  • Spring cleaning
  • Any time there's extra dust in the air

And it all works with a touch of a button.

Event-Based Air Cleaning - Cleaner air on your terms

One of the many advantages of an Aprilaire air purifier is the ability for you to control when and how it works. Most whole-home air purifiers work only when your heating or cooling system is running. But what if you're vacuuming and kicking up extra dust? What if it's allergy season, and you and your family are constantly sneezing?

There are special day-to-day situations that make the need for air cleaning more urgent. That's why we offer an Aprilaire Event-Based Air Cleaning Thermostat. It allows you to manage your air purifier with a simple-to-us control that's conveniently located in your living space.

Aprilaire Thermostats with Event-Based Air Cleaning

Aprilaire Wi-Fi Thermostats with ​IAQ Control provide the most convenient and accurate control of air purity and temperature. Event-Based Air Cleaning is integrated into the thermostat and easily controlled from a mobile device. You're notified when your air purifier filter needs replacement. The app also allows you to control other installed Aprilaire IAQ products for optimum fresh air ventilation and humidity levels and keeps you up-to-date about changing climate conditions in your home.
