Generally speaking, air purifiers do work. They do a great job at their intended purpose, which is to purify the air. Your results will vary depending on expectations and the make and model of your air purifier. If you have been shopping around for the best air purifier, you may be surprised by all the different brands and models. For example, the Homdox car air purifier is a great one for your vehicle, but not for in-home use. The reason is that the air quality isn’t as expansive as stationary models. 

And there are certainly plenty of unique models, including the Levoit LV-132 and the Smoke Buddy air filter.  

However, maybe there’s one question off the top of your head. Just how do air purifiers work? Read on to find out.

KEY TAKEAWAYS:

  • Air purifiers do indeed work, though this depends on your expectations and the type of purifier you use.
  • Modern air purifiers do a great job of reducing foul odors and eliminating risky allergens from the home.
  • These purifiers are also a great fit for snorers, as they can alleviate loud snoring throughout the night, though results will vary.

Do Air Purifiers Actually Work?

Air purifiers work quite well, as long as they’re in the room fit for their appropriate coverage. But, if you need an air purifier for a specific purpose, such as keeping the air clean for seasonal allergies or dust mites, you’ll need a much stronger unit. And, you’ll need the right type of unit for your needs.

For instance, if your air purifier removes smoke, you’ll have to know how to clean a tar air purifier, as tar is the result of the byproduct of smoke.

What is an Air Purifier?

Generally speaking, an air purifier is a device that sucks in air from a living space, filters it through a variety of means, and then pushes it back out to the atmosphere. The end result is purified air. And, your air purifier might have removed any smells.

Did you know that air purifiers remove dust and will work to lessen certain allergies? In fact, many great air purifiers work to remove airborne particles, pollutants, and particulate matter from the air, thus improving your indoor air quality. 

Warning

Before you buy a new air purifier, make sure it is rated to easily handle the size of the room you are considering placing it in.

This is done via filtration through filters. Many types of air purifiers can have a combination of pre – filters, carbon filters, and HEPA filters. Some air purifiers don’t use filters and use different technology to clean the air. 

Air purifiers are a massive boon to people with asthma. They can reduce allergy symptoms within an indoor space and improve overall health. 

What Air Purifiers Are Good For

Here are a number of things that air purifiers excel with. Keep this stuff in mind as you shop for a new model.

Purifying Air

This should go without saying, but modern air purifiers are great at, wait for it, purifying the air. This makes them a great choice for living rooms, bedrooms, infant rooms, office areas, and other spaces that place a premium on clear air. Before buying a new air purifier, ensure it is rated to easily handle the size of the room you are considering placing it in.

Eliminating Smells

Modern air purifiers do a fantastic job of eliminating nasty and unpleasant smells that have permeated your living space. Air purifiers make short work out of a wide range of odors, including smoke, mold, mildew, rotting food, pet excrement, and a variety of mysterious smells. If you really want to supercharge your air purifier’s odor-elimination abilities, be sure to buy a model equipped with a true HEPA filter and a diffuser.

Reduce Allergens

An air purifier could be a godsend if you suffer from seasonal or environmental allergies. These machines are purpose-built to trap and destroy common allergens such as pet dander, pollen, dust, and more. You should make sure the air filter is up to the task and err on the side of choosing a genuine HEPA filter.

By selecting a unit with a True HEPA filter, you’ll see a change in the frequency of your asthma symptoms. Most portable air cleaners may not have a real HEPA filter, so review these devices carefully before buying. 

STAT: The industry standard for air purifiers with a HEPA filter is that the unit must be able to remove at least 99.97% of particulates measuring 0.3-micron diameter in a lab setting. (source)

Good for Snorers

Modern air purifiers can help alleviate loud snoring, which is great if you are partnered up with a snorer. This is because these purifiers filter out allergens, allowing a snorer’s sinus passages to avoid inflammation throughout the night.

F.A.Q.S

Do air purifiers protect against wildfire smoke?

They will work against wildfire smoke, but it will depend on the power of your particular air purifier and the level of smoke you are dealing with. You may need to double or even triple up.


Do air purifiers work against COVID-19?

Modern air purifiers, particularly if outfitted with a HEPA filter, will trap and seal in COVID-19 virus particles. They will not kill them, though they should die once after a couple of days trapped in the filter.


Can air purifiers filter the outdoor air that enters your home?

Absolutely, though, it will depend on the level of air entering your home and the power of your purifier.
