What Are Whole House Purifiers?

Whole house air purifiers are larger versions of your typical portable room air cleaner. They are connected to your HVAC system allowing them to filter your entire home instead of on a room to room basis.

Their setup lets them run in conjunction with your furnace and air conditioner. While these systems have their own filters, adding a dedicated purifier improves their air cleaning capacity. Sometimes, by up to 100 times. This makes them more effective in getting rid of allergens, pollutants and toxins in the air.

It also means you and your family are able to enjoy clean air wherever in the home you go. As a result, you experience better overall indoor air quality throughout your home.

How Do They Work?

Whole house air purifiers cover an entire group of systems that are installed into you HVAC system. Their main function is to clean and purify the air in your home.

With this setup, you’re essentially adding a filtering unit to your heating and cooling system. In doing so, it automatically cleans the air indoors whenever you use the temperature control to cool or heat your home. The image on the right from illustrates how whole house air purifiers work.

Most whole house air purifiers fall under three main types.

  • Filter-based systems. These are set up in your HVAC and furnace. They also use your home’s air intake points.
  • Duct-based systems. These appliances are installed into the air duct paths. As such, they are placed before or after the air handler in your central HVAC unit.
  • Stand-alone units. These are set up in attics or closets. With stand-alone systems, additional air intake and exhausts will be installed into your home,

The one thing all three have in common is they are connected into your home’s central heating and cooling system. This often requires professional installation. Additionally, because of their size and power, whole house air purifiers are also more expensive compared to portable room air units.


Pros & Cons: Whole House vs. Portable Air Purifiers

In this section we compare the differences of whole house and portable air purifiers. Like all products, each has their advantages and disadvantages.

Whole House Air Purifiers


  • Full home coverage. They clean all the rooms in your home. So, you don’t need to move them from room to room.
  • Your family enjoys clean air all the time.
  • You don’t see the main unit.
  • They operate silently.
  • Once installed, there’s less maintenance involved. Many models require maintenance only once a year. Portable air purifiers in comparison need their filters to be cleaned or replaced every 1 to 3 months, depending on the product.


  • They’re expensive.
  • Most require professional technicians to install.

Portable Air Purifiers


  • Very affordable. They’re available in all price ranges. This allows you to buy them under $30.
  • They’re quick and easy to set up. Just place them down and plug them in.
  • They’re portable. You can carry them from room to room easily.


  • Many products don’t have the capacity to effectively clean the air around you.
  • They vary in cleaning ability. Some are designed for large particles only. Others can’t trap dust mites, smoke or mold spores.
  • They’re limited to cleaning the air in one room.
  • Some units are loud. Others are quieter but still make a buzzing sound. This can be an issue if you plan to leave them overnight in your bedroom.
  • If you want to clean the air in more than one room, you’ll need multiple units.

Which one is right for you?

There are a few different factors to consider when choosing the one that’s right for you. These include:

  • Budget
  • Where you live
  • If you own pets or not

If you don’t have any pets, live in an apartment, and are on a limited budget, then a single portable air cleaner would be the best choice. However, if you live in a house and you own pets, then a whole-home air cleaner would be a more effective and cost efficient choice.


How Do Whole House Air Purifiers Help?

Whole house air cleaners are an efficient way of purifying the air you breathe. It does so by filtering your central heating and cooling system. Because these air cleaners are built into your home’s return air ductwork, they’re able to capture dirt, allergens and other contaminants way before these can circulate in your home.

The biggest advantage of using this type of air purifier is they cover all the rooms in your home. And, it constantly cleans the air.

In addition to constant full home coverage, whole house air cleaners offer a combination of filters. These are designed to take care of different types of air pollutants and contaminants.

  • Media filters. This type of filter traps the larger particles like hair and dirt. They’re the cheapest type available.
  • Electrostatic filters. These are for smaller particles. It uses charged particles to trap the allergens and particulates.
  • Electronic filters. These are high tech units. They’re similar to electrostatic fitlers. But, come with mesh wires that are charged. This attracts the particles like a magnet. Electronic filters are incorporated into your home’s ductwork. Their function is to catch the smallest particles including smoke. They’re more expensive but don’t need to be replaced.
  • UV filters. Specifically for killing germs. UV filters use ultraviolet light to eliminate mold and bacteria.

Depending on your needs and budget, you’ll be able to select a product that uses a combination of these filters.
