Things To Consider – Best Air Purifier

Operating Cost

The operating cost of the air purifier is one of the more important considerations that you need to keep in mind. While you’re going to have an added cost because of the extra electrical consumption, the total annual cost of running an air purifier is around $150 to $200 dollars when you figure both the cost of the filters and the electricity that it is going to take.

You will need to replace your filter about every 3 months. If you happen to buy a purifier that has a pre-filter, you may extend the life of it a little bit longer and find that you’ll have to buy filters less often.

Sound Level

This isn’t one that gets thought of a lot, but the sound level of the air purifier that you buy is going to be a pretty important consideration. If you are going to use it in a big room where you don’t really need it to be quiet, that’s one thing.

But if you are going to use it in your room where you sleep, then the quietness is going to be key. If you’re looking for the most efficient and quiet way to run the purifier, you’re going to find that you will be best off trying to buy a larger purifier and running it at a lower speed as opposed to cranking up a small air purifier.

Ease Of Cleaning

When it comes to using an air purifier, it’s important to make sure you are able to clean it with ease because it is crucially important to keep your air purifier clean. If you don’t, it’s not going to purify your air properly and you’ll be running it for nothing.

Most of the air purifiers that you find are going to have an easily removable tray and filter so you can change them and clean them with little to no effort. If you find an air purifier that doesn’t have these features, you might want to look at another one because if it is that difficult to clean, you’re going to find that you put off cleaning your air purifier.


While this should come as no surprise to you, one of the more important things to consider is what size air purifier you are going to buy. In general, this is going to be decided by what size room you are trying to purify. The bigger the room, the bigger the purifier you’re going to need to buy.

The air purifier is going to tell you how much square footage it is able to cover so in order to choose properly, you’ll want to make sure you know the square footage of the room you plan on using it in.

In addition, you might want to consider the size of the air purifier to make sure you have enough room to place it where you want it to. If you have a small space that it needs to go into, make sure you pay attention to the dimensions so you know for sure if it fits.

Added Features

Once you figure out what size air purifier you’re going to want to buy, it’s time to start thinking about whether or not you want to buy some of the special features that can come with it. While you may get some of these features without a ton of added money, some will come at a premium.

Some of the special added features that you might find include wheels and handles, digital controls. Multiple fan speed, timers, air quality sensors and so much more. These extra features can help make your experience much better overall.

HEPA Filtration

If you’re going to buy an air purifier, then you might as well buy the best one that you can find and that’s why you should try and find a purifier that offers HEPA filtration. High-efficiency particulate air, or HEPA, filters are 99.7% effective in removing particles that are at or larger than 0.3 microns.

HEPA filters are similar to a paper-like filter and they have fibers randomly positioned throughout in order to narrow the passage ways. Always try and find a HEPA filter that is true medical grade and is non-petrochemical. Study shows HEPA filter can eliminate cigarette smoke.


When it comes to finding the best air purifier, it is going to be really important for you to find one that comes with a prefilter. The prefilter is going to work to trap some of the large particles like dust, hair and pet dander.

While it certainly isn’t required to have one with your purifier, I highly recommend trying to buy a unit that has a prefilter because it is going to perform a lot better with that added filter.
