Guide for Buying the Right Air Purifier

While air purifier can be a very popular product, almost a must have in every home, there’s a few factors we need to know before purchasing one. Of course, aside from just the price and looks, what else should we look out for?

Below are the areas you should look out for.


High Efficiency Particulate Air (HEPA) filter

This is almost the crux of the entire air purifier and without a good functioning one, then sadly the air purifier may be as good as useless. This is because the filter itself helps remove more than 99.97% of particles which really helps purify the air.

HEPA Filter

HEPA filter illustration. Image source: Wikipedia.

As you can see from the diagram below, a human hair has a diameter of 40 microns. However, particles can be measured from 2.5 to 10 microns diameter using PM10 and from 2.5 microns and below using PM2.5, as such the particles are too small for you to see it without any special device.

Human hair

These very tiny particles can be trapped easily by your nose or even throat, however if you are unfortunate enough, those even smaller particles like PM2.5 can also slip through and enter your lungs. When this happen, you can expect all sorts of health issue.

In essence, without this filter, the air purifier is as good as useless and just for show. Most of the cheaper ones out there are not true HEPA filters as they may even labelled it as HEPA-like or HEPA-type.

Air purifier = (match) room size

Now what do we mean by this? You need to ensure the air purifier is suitable for your room size. Some air purifiers are designed to be used in smaller rooms as such it may not work well on bigger rooms, vice versa.


So how can you tell? Easy, refer to the air purifier specification sheet and look out for CARD (Clean Air Delivery Rate). This rate matters as the higher the number, the more air the device is able to filter per minute. The measurement may shows as either meters per minute or even expressed in cubic. Also, just in case you would also like to know the size of the particles it’s able to filter and how effective it can get, for this you may need to refer to the HEPA specification instead.

The general rule of thumb is you would want a CADR of at least 2/3 of your room area. So for instance if your room size is 90 sqft, you may need a CADR rating of at least 60.


Another point to take note is avoid air purifiers which uses ozone. Reason being, when it cleans the air using ozone, it might somehow impact the lungs causing cough or even breathing issue. This is especially important to note if someone is already having an existing lungs medical condition or suffering from asthma. If you have children or elderly in your home, then we highly recommend not to use one as they are more sensitive to ozone.

 You may find some air purifier that uses ion generators instead to clear the air, this may still be acceptable as the levels of ozone emitted is very low.


Fan Noise

One of the so called more premium air filter is those type which uses mechanical filtration. It works but making use of the fan to force the air through the filter in order to trap the particles then letting the air flow out. This kind of filtration is cost effective and proven.

Do note when purchasing such air purifier, you may want to take note of the fan noise. If the fan noise is a little too loud, while it may actually purify the air, it may also actually affect your sleep.

If you are buying it in a crowded mall, then listening to it directly may not be a good idea. While it may sound alright to you in the mall, it may not be the case once you’re back in home in your quiet room. As such, you may want to refer to the air purifier’s rated noise level.


Reputable Brand

Now how does this even matter? Well, the filter may clog over time and you may need to replace it periodically.

This is one of the maintenance cost required for using an air purifier. However, if you purchase an unknown brand, it may ceased to exist by the time you are looking for the compatible air filter to replace for the exact model which you purchased. Try purchasing from those known brands, some of which are listed above, so you may not end up with this problem in future.

What should I look for when buying an air purifier?

When you buy an air purifier, consider the size of the room and the coverage area of the purifier you choose. Also, look for the ACH (air change per hour) of the purifier before you purchase. Your budget should be another major factor, as well. If you don’t want high-end features and are just looking for a normal purifier, then you can find lots of mid-range options. Air purifiers are a long-term investment, but that doesn’t mean you have to spend huge bucks on the purchase.
