Buying Guide

There are various types of air purifiers available on the market. And with the passage of time and the introduction of new technology features, the options have become even more overwhelming. However, there are some important features that you need to consider before or finalize your choice these are listed as follows,

  • Coverage area

The most important feature of an air purifier is area coverage. There are several units you can find that cover different areas. You can either go for a unit made for a small bedroom or you for a unit that is designed for a dorm room. Ensure you measure the size of your room and choose the unit accordingly.

  • Size and footprint

Some units are by design very large in size and you have to be sure whether they will fit in or not. If you already have compact space then a big unit is not going to work for you. You can use a smaller unit and place it on the table. Of course, if you have larger rooms available you can opt for bigger units.

  • Versatility

Also, consider a unit that can handle all types of allergens and microbes. And for that, you need to look at the filter size and how small of a microorganism it can eradicate. In most cases, 0.3-micron filters are suitable for most applications but you can also go with 0.25 microns or 0.2 microns air purifiers. Apart from that your unit must be able to take care of any odors or smells as well.

  • Filter replacement

In some seasons you need to use your air purifier a lot. And with more use, the filters will get dirty pretty quickly. Therefore, you will have to replace them frequently. Still, a good quality air filter will make sure you don’t have to replace your filters that frequently. Make sure you go for a unit that makes you change the filters twice a year or so.

  • HEPA filtration

This is the most effective air filtration technology and helps in removing up to 99.97% of particles and allergens from the air. It is so effective that HEPA has become a standard for air purification units.

  • Activated carbon filter

Another very important feature is the inclusion of activated carbon or charcoal filters within the filtration system. This filter is present in most 3-stage filtration purifiers and is very effective in alleviating any odors or smells instantly.

  • Additional features

Some of the purifiers also come with some additional features that include automatic fan speed, UVC light, an indicator for filter life, and an automatic shut-off timer. With these features, you can enhance your home’s air purification even further.

How often should I use my unit?

You can run your air purifier at regular intervals if you have a small space. For larger spaces, you will have to run it more often. For better results, you can pair your air purifier unit with an air quality monitor and see how often you need to run your air purifier.
