Best Whole House Air Purifiers

What Is a Whole House Air Purifier?

A whole-house air purifier is a filtration system that connects directly to your existing HVAC system. As air circulates through the system, the filtration device removes particles, including:

• Dust

• Dander

• Pollen

• Mold spores

• Other pollutants

Unlike standalone products, connecting to the HVAC system allows the system to improve air quality throughout your entire home.

What’s the Difference Between Portable and Whole House Air Purifiers?

Portable air purifiers are devices that typically plug into the wall and sit on the floor in a particular room. They are usually designed to clean a small area, such as a single room. Whole-house systems connect directly to your HVAC system and work to clear your entire home of harmful allergens and pollutants, regardless of room size.

Why Is a Whole House Air Purifier Important?

According to the United States Environmental Protection Agency (EPA), indoor air quality can sometimes be worse than outdoor air quality. With most people spending up to 90% of their time indoors, it's extremely important that they maintain the indoor air quality at a safe level.

While many homeowners prioritize physical home security, taking steps to improve indoor air quality is another proactive way to protect what matters most.
However, before you buy an air purifier, be sure to review and compare its capabilities with other top units on the market, as some are more efficient than others.

Can Whole House Air Purifiers Reduce Allergens and Dust?

Yes, most whole-home air purification systems use HEPA or advanced electronic filtration systems that capture dust, pollen, pet dander, and mold spores, reducing both allergens and dust. Some models trap particles as small as 0.1 microns, significantly reducing allergy triggers and improving overall air quality.

Do They Help With Pet Dander and Odors?

Yes, whole-home air purification can help with pet dander and odors. Models equipped with carbon filters are especially effective at reducing pet odors. Some feature carbon filters in their standard purifiers, while others require an add-on device for odor control.

Can They Improve Indoor Air Quality Year-Round?

One of the major benefits of a whole-house air purification system is that it works year-round. Whether you’re running the heat or the air conditioning, your system continues cleaning the air as it runs through your ducts. Be sure to ask your installer about maintaining your device during variable weather conditions.

What Should You Know Before Installing One?

Before installation, ask your service provider about:

• Initial, upfront costs

• If professional installation is required

• If the system is compatible with your current HVAC system

• Electrical requirements

• If the system will fit in your home

• Speed settings

• Sound generated by the system

• When to change or clean filters

How Much Does a Whole House Air Purifier Cost?

Whole-house air purification systems can cost anywhere from $700 to $2,500, depending on your location, filtration type, and installation requirements. While some models cost less upfront, others are more efficient and effective, making their higher upfront cost worth the expense in the long run.

Do You Need Professional HVAC Installation?

Most whole-home air purification systems require or recommend professional installation. While it is tempting to attempt a self-installation in the interest of savings, doing so will void your warranty and may lead to operational malfunctions down the road.

How Often Do Filters Need to Be Replaced?

Filtration replacement is unique to each filter, system, and home. Most filters are designed to last 6-12 months, but may require more frequent changes in high-particle areas. Some units feature reusable filters that you can clean, but often require more frequent maintenance than disposable filters.

Will It Increase Energy Bills?

Most modern whole-home filtration systems are designed for energy efficiency, minimizing additional costs to your monthly bills. While some filters will increase airflow resistance, proper maintenance will minimize this effect on your HVAC system. Be sure to inquire about estimated increases in your monthly bills prior to installation.
