Tips on Choosing a Whole House Air Purifier
Choose Air Purifier for Whole Home
Make sure that you are choosing a purifier that will clean the air in your whole home. If you are choosing a unit that only cleans an area smaller than your home, you won’t notice results and will likely still see dust and experience allergy symptoms.
Decide what filter is best for you.
HEPA filters are widely regarded as some of the best in the industry as they capture even the most minute pathogens and particles in the air. Ozone filters are extremely powerful at cleaning the air, but they can be harsh and cause nausea if you’re home while the system is running.
Know how loud the unit is. Especially if you’re planning on keeping the unit in your bedroom, you’ll want to make sure it either emits a white noise or is very quiet.
The brightness of the lights on the unit
Additionally, consider the lights on the unit too. They might keep you up if they are very bright!

Whole House Air Purifier FAQ
Most people get sick or have allergies and turn to medications to fix their issues. They don’t realize that the problem might be the air in their own homes!
Mold, mildew, and bacteria are constantly floating around in your air, just waiting to get into your body. Using medication will only put a band-aid on the problem.
By using a whole-home air purifier, you’ll remove these pathogens from the air and also stop their growth entirely.
In addition to that, pet owners and smokers might notice harsh smells in their homes that are extremely difficult to remove. If you simply use surface-level chemicals, the smells will remain. Using an air purifier will completely solve this problem for you.
First, determine how large your home is. If you just purify one room in your home, you’re going to be fighting a losing battle.
You need a purifier that can take care of the air in your entire home so you’re fighting back against the pollen, dust, mold, and more.
In this article, we’ve specifically highlighted the airflow that each unit can cover. For some, it’s a small area of 100-400 square feet.
Others can handle more than 3,000 square feet. If you have an apartment, a smaller unit might suit you. However, know that the larger your home is, the larger the unit you’ll need.
If you’re buying a whole-house air purifier, you typically don’t have to worry about where to put the air purifier. It will connect to your HVAC system that is already in your home. It will clean the air as you heat or cool your home down.
However, there are some models that do sit inside your home. You might choose this because it is less expensive than getting a purifier that connects to your HVAC system.
If this is the case, it is recommended that you put the unit in the room that you are in the most, perhaps the living room or even your bedroom.
