Air Purifiers Buying Guide in 2022


An air purifier works by removing harmful pollutants from the air around you. It does this by using a filter and fan to draw in air, capture particles in the filter, and then blow out clean air. A HEPA (high-efficiency particulate arrestance) filter is one of the most effective ways to remove dust, pollen, mold spores, pet dander and other contaminants from your home's indoor environment.

How to choose the right air purifier for your home

To find the right air purifier for your home, start by choosing a size. If you live in a large house, get a larger purifier than if you live in an apartment.

Next, determine which type of pollutants you need to remove from the air. Do you want to filter out dust and pollen? Do you want to get rid of cigarette smoke or pet odors? Answering these questions will help guide your decision-making process when comparing different filters and brands.

Also consider what kind of warranty is offered with the product. Some companies don't offer any kind of coverage on their products; others offer up to five years' worth of protection against damage caused by normal wear and tear—such as parts breaking off due to regular use over time—to ensure that consumers aren't stuck paying full price for something that only lasts six months before needing repair or replacement parts replaced themselves (which can end up costing even more than just buying a new unit altogether).

HEPA air purifiers and what you need to know about them

You probably already know that HEPA air purifiers are the most common type. But what do you need to know about them?

HEPA stands for "High Efficiency Particulate Air," and it's used to describe filters that contain 99.97% of particles down to 0.3 microns in size (about 30x smaller than a red blood cell). These filters are able to trap all sizes of airborne particles and allergens, including mold spores, pet dander, dust mites and smoke particles from cooking fires or other sources.

The effectiveness of a HEPA filter depends on three factors:

  • The size of its pores;

  • How many cubic feet per minute (CFM) air it can move through itself; and

  • The amount of time it takes for each particle trapped in the filter to pass through it again after being removed by one particle's impact with another surface area(s).

Household air pollutants explained

  • Particulate matter, also known as PM, is a mixture of solid and liquid particles that are suspended in air.

  • VOCs (volatile organic compounds) are chemicals that evaporate easily and can cause health problems when inhaled.

  • Toxic gases include carbon monoxide, sulfur dioxide, nitrogen dioxide, ozone and hydrogen sulfide.

  • Mold is a type of fungus that grows on surfaces where there's moisture or humidity—like an attic or basement. It starts growing on dead organic matter such as wood or paper products like cardboard boxes and papers/paint brushes etcetera that have been left around for too long without being cleaned up properly first time round before being stored away for future use perhaps because there wasn't enough room left over inside our house anymore after adding all those new things from last year's Christmas present list before cleaning out some old rubbish kept inside the garage instead while throwing out anything else still lying around which needs replacing soonest possible after making sure everything else already has found another place somewhere else instead by now hopefully meaning we won't need any more space afterwards either when moving into somewhere else soon after finishing up here today although we might need more room anyway once we finish unpacking everything else too so maybe it'd be better just leaving these things behind rather than moving them again later on down another street instead since none of us really know beforehand if this will happen yet though so maybe just leave us alone until then okay?

Top 8 Household Air Pollutants and Their Effects

  • Dust mites. These microscopic pests thrive in warm, humid environments and can cause an allergic reaction in some people.

  • Pollen. This pollen is shed by plants and trees and can trigger hay fever or asthma attacks in sensitive individuals.

  • Mold spores. Molds grow easily on damp surfaces that have been exposed to moisture, mold spores are capable of triggering allergy-like symptoms in some people (such as sneezing or wheezing).

  • Smoke from cigarette smoke, fireplaces and wood stoves. Smoke contains gases and particulates which irritate the lungs when inhaled over time; it also contains carbon monoxide which reduces the amount of oxygen reaching your blood stream making you feel breathless after strenuous activity such as exercising or walking up stairs quickly - so it's best not to exercise immediately after smoking!

Smoking also increases your risk for developing cancer (especially lung cancer) because toxins from tobacco smoke build up over time causing DNA damage - these damaged cells then start dividing uncontrollably leading them becoming cancerous tumours within our bodies."

Why You Should Consider Buying an Air Purifier for Your Home

Air purifiers can help you breathe easier, sleep better and live longer. They can also reduce your carbon footprint and save you money on energy bills.

  • Breathe easier- Polluted air can make breathing difficult. Inhaling certain particles in the air has been linked to lung cancer, asthma and other respiratory diseases. An air purifier may help clear some of these particles from the home environment, allowing you to breathe easier.*

  • Sleep better - If you feel tired during the day because of poor sleep at night, an air purifier may be able to help by reducing airborne allergens—including dust mites, pet dander and pollen—that may cause allergies or asthma symptoms.*

  • Live longer - Air quality is especially important for those who have pre-existing respiratory conditions like asthma or COPD (chronic obstructive pulmonary disease). Having cleaner indoor air could lead to a reduced risk for health complications in these individuals.*

You can purchase a home air purifier that is the right size for your needs

When you choose to purchase a home air purifier, there are many factors that come into play.

  • The size of your home

  • The size of the room or rooms you want to use it in

  • How many people will be using the room at one time

  • The type of air purifier you want (HEPA, UV light)

  • The type of pollutants you want to remove (smells, smoke, dust)


The air purifiers we have discussed can be found in many different sizes and styles. If you want something that is easy to move around and doesn't take up much space, consider buying one of the smaller models. If you prefer something that is more powerful or has more features (like a timer), then go for one of the larger units instead.
