How to Choose an Air Purifier ?

Buying an air purifier for the first time? Don’t worry, this guide will get you to ask the right questions for your ideal air purifier. 

Air purifiers can be used for many purposes - dealing with allergies, improving indoor air quality, to get rid of pollutants (especially when you have children and pets at home), and more.

Air purifiers remove pollutants, dust, pollen, and pores from the environment. But the most important thing to remember is that air purifiers purify - but do not clean - the air. Careful consideration of the factors we identify below is important so you don’t breathe in other harmful gases or volatile compounds that may come from the air purifier itself.

The Three Main Types Of Air Purifier

Ionizer air purifiers are generally inexpensive, but also the least effective air purifiers because they simply make the particles fall to the surface in the room. So your air will feel fresher, but the impurities/allergens are still in the room and open to inhalation. Nowadays an Ionizer is generally only found as an added extra on a Hepa Air Purifier (see below). If you have an Ioniser already you will probably have noticed a build up of black deposit around the machine where the particles have been attracted to the unit and stuck to the nearby surfaces. In general an Ioniser on its own is not the most effective way of cleaning a room, but an Ioniser as part of a Hepa Air Purifier is a good idea and a much more common sight nowadays. 

The real power behind an Ionic air purifier is the fact that it can remove particles as small as .01 microns in size from the air. This is 3x smaller than a HEPA device.

Hepa Air Purifiers ( High Efficiency Particulate Air Filter )

Hepa Filter air purifiers offer hugely better air cleaning efficiency than Ionizers. The contaminated room air is sucked into the machine and through the HEPA filter by a fan. The filter collects over 99% of the contaminants (allergens,pet dander,dust mites, etc) and the cleaned air is then pushed back out to recirculate around the room. The upside of a good hepa air purifier is it's ability to filter out huge amounts of airborne contaminants for a relatively low cost. One downside however is the noise factor, a cheaply made Hepa machine can sound up to 10 times louder than an equivalent well made one. The more specialist brands like Stadler Form or Boneco for example tend to be quieter than the mass produced lesser known ones.  The Blueair range of Hepa Air Purifiers are simply the most powerful, quiet and energy efficient units you can buy with awards galore from all over the world. With any Hepa based machine, you will need to replace the filters regularly to keep the air cleaning efficiency at it's highest level. So always check the replacement filter costs before buying.  

Air Sterilizers (air sterilisers)

Air Sterilizers like the Airfree Air Purifiers clean the air to the highest possible degree when it comes to the tiniest, most harmful pollutants like viruses and bacteria. They are also completely silent in operation and have no filters to replace. The downside of this type of unit however is that it shouldn't be moved from room to room regularly as it takes too long to 'get up to speed' after being repositioned. Also, if your problem is larger 'visible' dust particles then these units are not actually the best option as they are not designed to remove these larger heavy particulates. In this case you should opt for a Hepa air purifier (as above). In summary, choose an air steriliser if you are concentrating your efforts on one specific room such as a bedroom and want the unit to be silent and able to destroy viruses, bacteria and other tiny weightless harmful pollutants. 

Your Budget

Determining your budget before you decide to choose the right kind of air purifier is essential. Buying the best air purifier might cost more money than anticipated, so knowing what’s the market value of standard to professional air purifiers will definitely help you.

This also includes operating cost as well as the price tag of air purifiers. The operating cost of any extensive portal models depends on usage. A recent report that evaluated people’s willingness to pay for air purifiers showed that those who can afford to invest in a higher-priced air purifier for cleaner air will do so unquestionably.

Choosing The Correct Size

It’s important to measure the room you want the air purifier in before finding the right purifier size. You can calculate by taking the square footage of the room into consideration. By measuring both the total length and width (in feet) of the room and multiplying both numbers together, that is length x width, can you determine the total square footage of any room.

The last important step is to decide where to place the air purifier. If you want a portable air purifier for many rooms, it’s important to calculate the average square footage of each room. That way you can buy an air purifier that comes with caster wheels and handles for better transportability.

What’s The Noise Level?

You must have heard someone complain about a noisy air purifier at least once in your life. It’s not surprising to come across a silent air purifier, but that doesn’t mean it’s impossible. It’s important to take the noise level into account when choosing the right air purifier for your home. Based on the amount of noise the air purifier produces can you decide which room to put it in.

That said, what do you need to know about noise rating of an air purifier?

The kind of sound an air purifier produces is not mere sound, but it’s the air pressure waves that originate from the vibrating air purifier fan inside the appliance. This noise is oftentimes overlooked, but sometimes the noise increases in intensity causing an unpleasant and screeching sound.

To be able to measure the noise level of an air purifier, you have to look at the decibels or dB level of one. Even the quietest air purifier comes with a dB level so knowing it is critical to the air purifier buying process. The quiet sound noise levels for an air purifier is 15 to 36 dB, based on one report. 

Meanwhile, anything between 50 to 90 dB ranges from the noise level of a refrigerator to that of a lawn mower. According to one study, noise levels above 60 dB are considered too loud for humans to live with. 

All air purifiers come with a concise decibels rating for consumers. This level with give you a point in place when you’re making a final decision, especially when you’re buying an air purifier for your bedroom. A place where only the sound of traffic or birds chirping is acceptable!

On an ending note, finding a universal dB level for an air purifier is not enough. Like most features, this too is a subjective factor that depends completely on each individual. You might be comfortable with a 60 dB level while others may find it unpleasant and trying.

Air Purifiers to Avoid!

Avoid anything that makes a song and dance about things like having a 'Five Stage Air Purification System!' etc. These are almost always low quality, mass produced items with little or no genuine independent proof of their worth. Be careful, as sometimes they are priced fairly high too, which gives the impression that they must be somehow better than other less expensive machines. If in doubt always check for independent test results - not the manufacturers own 'test' results as these carry little genuine credibility. Ultimately the best air purifiers will only use a  one or two stage filter system ( never five, six or seven). Also, a good air purifier will never need to use UV ( Ultra Violet ) technology to clean the air, these are just cheap alternatives designed to sound fabulous, but in reality are doing very little.  

Small Air Purifiers with Big Claims

Be wary also of compact air purifiers which claim to be able to purify large rooms. This is a physical impossibility. If you think about it a very small air purifier can only contain a very small fan. A small fan simply cannot move enough air through the filter frequently enough to actually work. Yes, granted there will be some level of clean air coming out of the machine, but the majority of air in your room will remain untouched and unfiltered as the air purifier is simply not able to reach the farthest corners of the room. Again, don't be fooled by a compact air purifier with a fairly high price- the laws of physics still apply!
