Are you looking at getting a clean home air purifier for your home? Many homeowners look into buying them, as they worry about the quality of the air and the effect that it has on allergies that they have. They can offer a lot of benefits, but it's important that you know how they work.

Here's how a clean home air purifier works, and how you can use one.

What Is A Clean Air Purifier? 

Firstly, what is a clean home air purifier? These are machines that are designed to take in air from the environment around them, clean it, and then push it back into the atmosphere. The idea is that they capture any pollutants in the air, and clean it. 

What can a clean air purifier trap? Typically, you'll see most air purifiers on sale offering to trap dust, dirt, pollen, and other allergens. That's why they've become a popular way of clearing the air of these allergens, to help those repository issues. If you're someone who's considered using purifiers to help with hayfever, asthma, or other allergies, then it could be the right option for you.

How Does A Clean Air Purifier Work? 

How do these purifiers work, then? It actually depends on the type of purifier you're using. There are two main types of purifier that you can use, to get the air in your home cleaner.

Air purifier filters: These are the most common type of purifiers that you'll see available for your home. These use a filter, and that's what traps the allergens that are in the air around you. If you have a HVAC system, you'll see it's most like the filters that they use. 

The purifier draws in air from the environment around them, and them draw it through the filter. At this point, anything that's larger than the pores in the filter will be trapped here. Then, the cleaned air is expelled.

There are several different types of filter out there, so you'll want to make sure you're getting a purifier with the right one for your needs. The most basic filters will be able to trap larger clumps of dust and dirt. These filters get more and more efficient, all the way up to HEPA grade filters.

Electrostatic precipitating cleaners: This is the other main type of air purifier that you'll come across. Rather than using air filters, these use electrical attraction to clean the air. They will draw in air with a fan, and then charge the particles within it. There are several plates in the filter that carry the opposite charge, and as the air passes by them they attract the contaminants. The air is then expelled, being cleaner than before.

That sounds good, but the problem is that these purifiers create ozone as a by product. Ozone does carry several different health issues, so you'll want to consider these when choosing an air purifier.

Which one should you use? This will depend on you and your needs, but typically you'll want to go with an air purifier filter. These are the safest option, as they don't create any by-products when they filter the air. Instead, they just draw the air through the filter, and that's what catches the allergens.

Getting The Right Filters 

Once you've decided to get a filter air purifier, you'll need to next find one that uses the right filter for you. There will be all kinds of filters available to you, so you'll need to find the one that works best for your needs. In most cases, it's always best to go with a HEPA filter.

These filters, also known as High Efficiency Particulate Air filters, are able to capture particles of vary sizes. That's thanks to their design. They use a multilayered net, which is made out of fine fiberglass threads. You'll see that they're actually thinner than a strand of human hair.

As the filter netting is so dense, it makes it very difficult for particles to make their way through. Typically, larger particles will crash into the fiber and so be caught by impaction. Mid sized particles will be captured by interception, which is where the particle touches the fiber and is caught. Ultra fine particles will be captured as they zig zag through the filter, eventually getting caught. This is also known as diffusion.

As you can see, HEPA filters offer the very best protection against pollutants and allergens. As such, you'll want to use an air purifier that uses a HEPA filter to get the very best results.

Helping Improve The Air In Your Home

There are several ways you can improve the air quality in your home, as well as using an air purifier. Here's what you can do to get the best results possible: 

Ventilate often: Keep windows open as often as you can, as this will help fresh air flow in and through your home. With several windows open, stale air will be pushed out by fresh air. This will also stop locking pollutants and allergens from being locked into rooms.

Change air filters regularly: Just as you would with your HVAC filter, you'll want to change the filter in your air purifier regularly. Over time the filter will collect more particles, and at some point will be too clogged to be able to work. Change the filters out or clean them before this happens.

Keep vacuuming: Allergens are well known for sticking to carpeting, so you'll want to vacuum often. If you can, make the switch to a well rated vacuum cleaner that uses a bag, and is HEPA rated. That will help trap allergens inside, and stop them from escaping back into the air.


Now you know all the basics about how an air purifier works. They can be an effective tool in stopping allergens getting into the air, so look into getting an effective model today. Along with good ventilation and cleaning, they can do a lot of good.
