Best Places to Use an Air Purifier

You must be thinking why does it matter? Well, the location where you place your air purifier matters a lot. The good thing about having a portable one is that you can use it in multiple locations. You can take it from room to room as you like.

In the Kitchen or Bathroom

Generally, the best place to use an air purifier would be the one which generates the most odors. Kitchen and bathroom are the two rooms of the house which are the source of most odors. Therefore, it is good to have an air purifier with a UV and HEPA filter. Both of these filters combined will get rid of odors and microbes that these two places of your house host.

In the Smoking Lounge

This is pretty self-explanatory. The smoke lounge or whichever part of your house you smoke in would be an ideal placement for your air purifier. It is going to get rid of all the smoke and the odors as well.

Do Not Put Near Electronic Devices

This is suggested as some electronics work on similar frequencies as your air purifier and therefore, they could be a hindrance to its functionality. Thus, it would be ideal for you to place it away from your television, computers, stereo equipment, etc.

In the Pet Area

Your pets shed dander and they produce unpleasant odors. Therefore, it would be ideal for you to place an air purifier wherever your pet normally resides or sleeps within the house.

How to Choose a Portable Air Purifier?

So what are the things you should keep in mind to find your perfect air purifier? It surely can be a confusing thing to buy. An air purifier is a personal purchase, however, there are some factors you need to look for in a decent air purifier.

Air Cleaning Technology

There are a ton of filters that air purifiers come with, and not all are useful for you. According to the needs of your area, you should decide which filter to look for. For example, a HEPA filter is generally good for cleaning super small particles and is necessary to have in your filter. Furthermore, if one smokes, then it is important to invest in an air purifier that has a carbon filter to get rid of the smoke and odor left behind from smoking.

Size and Portability

Industrial-sized air purifying units are hard to store, hard to clean, and hard to move. Therefore, it is ideal to invest in an air purifier which is portable if you need to move it from room to room. The larger the purifier, the harder it is to blend in with your surroundings. Particularly, if you are living in a small space, it is better to invest in a portable air purifier.

Noise Reduction

It's important to choose an air purifier which produces minimal noise. Units with high fan speeds tend to produce more noise. It can be quite upsetting for people, especially the elderly if you are placing the air purifier in their room. Thus, this is another aspect to consider before buying one.It can also disturb sleep or bother children and pets if your unit makes too much noise.

Odor Removal

Another feature to look for in an air purifier is how well it can remove odors. The ideal air purifier would be good at getting rid of unpleasant odors like those produced by pets, smoke, etc.
