Air Purifier Buyer’s Guide
While windows and doors do a good job of keeping our homes fresh, the reality is that no one wants to have their windows open in the middle of winter! Plus, if you live in a big city, having a window open can be more detrimental to the interior air quality than having it closed.
Fresh air is essential, and homes that are filled with dust, smoke remnants, pet hair and other allergens can be very harmful to those with sensitivities. An air purifier filters out specific pollution in your home, cleaning the air then sending it back into the room.

Your new air purifier will have a set coverage area, usually measured in square metres. If you have a big home with open plan rooms, look for a purifier with a larger coverage area.
If you plan on using your purifier in smaller bedrooms or studies, compact and portable air purifiers are more practical.
An air purifier must have an effective filtration system that reduces the allergens in your home. HEPA or HyperHEPA filters are the most efficient, while HEP-like or HEPASilent filters are suitable for smaller rooms.
Some purifiers will have just one filter, while more expensive models designed for open plan offices may have up to five filters.
Your air purifier will likely come with a range of modes and settings. Even the most basic purifiers can come with more than one fan speed, and this should be easy to adjust.
Other modes include a sleep mode, where the purifier runs quietly, and an automatic mode, where the purifier will adjust its fan speed and power levels as the air quality improves.
Those with built-in sensors should spring to life as soon as they detect that the air quality has reduced.
Ease of Use
Air purifiers are generally very easy to use.
Those controlled by smartphone apps or voice activation are undoubtedly convenient, but they can be more confusing for technophobes!
Look for an air purifier with a simple display and one that will turn on and off automatically if you are concerned about ease of use.
Some air purifiers are remote controlled, allowing you to switch them off, on and adjust the fan settings from a convenient distance.
Special features include auto detection, a night time mode and integrated timers.
Purifiers that can be controlled via smartphone can often be set to run on a schedule. Some air purifiers will let you know when the filter needs replacing.
Air Purifiers FAQ
What is an air purifier and how does it work?
Air purifiers are designed to improve the air quality in your home, removing harmful particles and allergens from the air and then sanitising them.
The integrated filter captures airborne particles using the internal fan. The filters remove harmful particles like dust, pollen and bacteria, then circulate the purified air back into the room.
How to tell if your air purifier is working?
There are a few simple ways to test if your air purifier is working. The first is to check that the fan is working. This should be blowing out clean air.
If you think your air purifier has stopped working, it may be because your filter is damaged or has become very clogged and needs replacing. If your purifier has a filter indicator, check that it’s not alerting you. If there’s no indicator, you can remove the filter and check for discolouration, dirt or black spots.
Finally, investing in an air-quality monitor is a good way to check that your air purifier is working. Keep the windows and doors closed, and monitor the air quality over a period of time with the purifier turned on. Your purifier should bring the air quality down within a few hours.
How to clean an air purifier?
If your purifier has a permanent filter, it can probably be cleaned using warm water.
To start, turn off your air purifier and unplug it from the socket. Clean the filtered air outlet using a brush, then remove the grill and wash your filter using warm water.
Allow it to dry naturally. If your filter cannot be washed, clean it using a vacuum cleaner.
Put your filter back into the machine and replace the front grill, then wipe the outside of the purifier with a cleaning cloth.
An air purifier is a must-have if you suffer with allergies or hay fever. Homes with pets can also benefit hugely from a purifier, as the cleaner air is more pleasant for both family members and guests.
For its contemporary design, large coverage area and quiet operation, the Alen BreatheSmart Classic Air Purifier is our top recommendation for the best air purifier on the market.
