5 Things To Consider Before You Buy An Air Purifier

If you suffer from asthma, allergies or other similar conditions, you may want to try out air purifiers. The role of these devices is to remove pollen, smoke and dust from the environment. So, you can check out a good air purifier. When looking for one, make sure you consider the 5 things given below.

1. Use the Air Purifier properly

First of all, it’s important to keep in mind that these units can be beneficial for you only if you follow the proper operation method. The right way is to keep the unit switched on 24 hours a day at high settings. If you have installed one in a small room, expect it to clean the air in half an hour. On the other hand, bigger rooms may require at least 2 hours to do the same job.

Since these units don’t burn a lot of energy, you don’t need to worry about your utility bills. Therefore, you can keep the unit running for hours without worrying about your budget.

2. Don’t buy Ozone-based Air Purifiers

Some units generate unstable ozone gas. This gas is not good for your health due to toxicity. If you are exposed to this gas for a long period of time, it can cause lung and throat infection. Young kids are more prone to the effects of ozone. In some cases, prolonged exposure to ozone may cause damage to your lungs as well.

What you should do is opt for purifiers that make use of HEPA filters. These filters are designed to filter at least 99.97% airborne particles.

3. Maintain Hygiene

Another misconception about these units is that they eliminate the need to clean your office or house frequently. Although these air purifiers can suck up the pollen, dust and dander particles, know that you still need to clean your home or office. Some heavy pollutants are attached to the floor and wall of your house. They can only be removed by manual cleaning. Therefore, you should follow your house cleaning routine even after you have installed an air purifier in your home.

4. Change The Filters

Like all other types of devices, air purifiers require regular maintenance. One of the most important maintenance aspects is to change the filters in a timely fashion. If your unit has a HEPA filter, make sure to replace it in time. Actually, these filters get clogged with regular use, which may have a negative impact on the functionality of the device.

5. Check the Ratings

Before you opt for a device, make sure you read the ratings, such as CADR rating. This will give you a pretty good idea of the efficiency of the unit when it comes to filtering the particles. This rating must be 100 or it may not be useful for you.


Long story short, most air purifies are quite safe to use. However, make sure you do your homework before placing your order. After all, you don’t want to end up buying a device that won’t work for you.
