Frequently Asked Questions

How Do Air Purifiers Work?

Air purifiers use a fan to suck in air. They have multiple filters that are designed to catch and trap pollutants, removing them from the air. Once air moves through the filters, it circulates around your space as clean air.

How Frequently Do You Need to Change the Filter on an Air Purifier?

Yes, you will need to change the filters in your air purifier. How frequently the filters will need to be changed will vary based on the product you choose and the air quality in your home.

What Are the Different Types of Air Purifiers?

There are five main types of air purifiers. They are

  • HEPA Filters: This option is designed to trap particles and pollutants. They are often made using foam, cotton, or fiberglass. With this option, you will likely need to change the filters frequently.
  • Electrostatic Filters: An electrostatic filter works by charging pollutants in the air. Then, these pollutants are gathered within the machine. With this type of filter, you can often wash out the plates that catch the pollutants and reuse them. This type of filter produces ozone and this is considered its most serious drawback.
  • Activated Carbon Filters: Activated carbon filters are designed to be used in conjunction with other types of filters. With this type of filter, gasses and odors are trapped in the carbon inside the filter, thus removing them from your air.
  • Ionizers and Ozone Generators: These filter options work by making charged ions or ozone. When particles in your air come in contact with the ions of the ozone, they also become charged. So, instead or remaining in the air, they will stick to the surfaces around the room.
  • Ultraviolet Lights: With a UV light purifier, you can also eliminate microbes and some viruses. UV lights are frequently installed within an HVAC system.

Where Should You Place an Air Purifier?

This will depend on why you want an air purifier and the type of space it is intended for. If you intend to use it to purify the air of your entire home, you will want to make sure that you pick an option that is rated for a larger room.

You should place it near the air intake for your HVAC unit. If you plan on purchasing an air purifier for a specific room in your home, a corner of the room is often a good place to put it.
