What is an air purifier and how does it work?
Air purifiers help to sanitize the air that contains pollutants, allergens and toxins. Air purifiers are commonly mistaken for filters but while filters only remove particles, air purifiers can sanitize them too.
The exact particles removed by an air purifier depends on the type that you choose. Certain air purifiers are made with filters that trap particles while others may neutralize particles in the air without filtering them first.
What are the types of air purifiers?
There are a few different air purifiers that you can choose from and we’ve described them in greater detail below:
UV air purifiers
These are air purifiers that use ultraviolet light to remove harmful air particles such as viruses and pathogens. If you’re looking to kill mould, germs or other bacteria, UV air purifiers are incredibly effective. Just keep in mind that since they use special light bulbs, however, they’d need to be replaced every year or so.
HEPA air purifiers
One of the most popular air purifiers out there, HEPA air purifiers come with air filters that effectively remove particles from the air in your home. In particular, they’re great at removing pollen, dander, mold and dust. While they can remove the vast majority of irritants in the air, the HEPA filters must be replaced every month.
Activated carbon air purifiers
Dealing with smokes, odors and fumes in your home? You’d want to consider an activated carbon air filter. These come with HEPA filters and can also remove particles from the air. They’re effective at removing odors, chemicals and smoke but aren’t as great at removing pollen, dander and dust.
Electronic air cleaner air purifiers
These work with your furnace or air conditioner to charge and trap airborne particles. Instead of filters, they trap airborne particles with static electricity instead. They’re great at removing a range of irritants from dust to smoke, fumes and more. They do, however, need to be professionally installed.
Who is an air purifier suitable for and what benefits does it bring?
Air purifiers have plenty of benefits as they allow you to have fresh and clean air within your indoor space. In particular, they:
- Great for allergy-sufferers: Allergy sufferers tend to be triggered by pollen, pet dander and dust mites in the air. Air purifiers can help with keeping the indoor air clean of impurities for those with allergies. Many individuals are of the opinion that having an air purifier has helped to minimize allergies.
- Ideal for those with asthma and respiratory issues: Air purifiers can help eliminate any microbes within the air that can cause asthma and respiratory complications. HEPA filters in particular can filter over 99.9% of allergens. In fact, air purifiers are considered to be the 4th most effective measure in preventing asthma in comparison to other appliances. If you’re not sure, you can always buy an air purifier and test it out.
- Helps to reduce any foul odors and smells in your home: If your home has any odd smells, odors or smoke, an air purifier can help filter the air and eliminate the smells, leaving you with fresh and clean air to inhale. In our opinion, activated carbon air filters are the best for smells and odors.
- Great solution for pet owners: If you’re a pet owner, you’d be dealing with a good amount of dander in comparison to someone that doesn’t have one – especially if you’ve got a pet that sheds heavily. Pet dander isn’t great for those with allergies and it can trigger health complications. With an air purifier, you’ll be able to eliminate these harmful particles with no problems at all.
Shopping Criteria for Air Purifier
Below are some of the shopping criteria that we’ve taken into consideration and comparison when calculating the score of each air purifier.
Sensors and Timers
In our opinion, sensors and timers are nifty yet important features to have when selecting the best air purifiers. Sensors can help with monitoring the level of indoor air pollution and maintain the air quality without having it to run 24/7. If the air purifier doesn’t have sensors, timers are equally useful as you can set the unit to run at certain times of the day. You should always test the sensors and timers of the air purifier you’ve purchased.
The last thing anyone wants is to deal with an overly loud air purifier. The products that we looked at all have a good range of fan speeds. You’ll want powerful air flow when you need to clean a room’s air quickly, but a gentle one when you’re using it in the evenings. Certain air purifiers also come with sleep mode that’s perfect for when you’re heading to bed, you can always experiment and test out the different fan speeds to determine which one you need.
The air purifiers we’ve selected cater to various room sizes. If you’ve got a larger room, you’d obviously want an air purifier that can clean your room’s air efficiently. On the other hand, if you’ve got a smaller room, you wouldn’t need an overly large air purifier. If you’re unsure, you can always buy a larger model first to test it out.
Filter Replacement Indicator
With most air purifiers, you’d need to replace the air filter at least once a month. If you don’t replace the air filter, it’ll greatly reduce the effectiveness of your air purifier. To help ensure that you replace your air purifier consistently, we’ve taken the filter replacement indicator feature into consideration when selecting the best air purifiers.
Most of the best air purifiers out there have HEPA filtration and that’s something we’ve taken into consideration. HEPA stands for high-efficiency particulate air and is an effective filtration system that helps to trap very small particles. HEPA filters can trap at least 99.95% of particles ranging from dust to smoke and more.

Why is an air purifier important?
In a nutshell, air purifiers can help with refreshing stale air and reduce any chances of potential health issues (such as allergies and asthma) that can be triggered by indoor pollutants.
Where should I place an air purifier?
Typically, you would place your air purifier in the middle of the room if possible. There should be at least a foot of space from the walls so that your air purifier can effectively clean the entire room instead of just a small corner. Interestingly, the less number of items you’ve got in the room, the more effective your air purifier will be, but you can always play around and test it out.
