How to pick the best air purifier

When shopping for an air purification system, there are a number of factors that you need to consider. They include:

Operating costs

Air purifier operating costs fall in the ranges of between $150 and $200. These costs are mostly for electricity and filter replacement which is normally done after every three months. To cut on costs, consider air purifiers that are energy star rated and ones that have washable filters.

Type of Air Purifier

Most air purifiers employ two types of filtration technologies. These include HEPA and Carbon filtration. Consider an air filter that employs both technologies if you want to achieve clean air without any odors. True HEPA air filters help remove even the tiniest pollutants in the air with an accuracy of 99.97%.

Room size

When shopping for an air filter, consider the size of the room you need to place the air purifier. If your apartment size is 600sq. ft., choosing an air purifier that’s designed for a 150 sq. ft. room won’t do the job perfectly.


Of course you don’t expect to get a purifier that small enough to fit in the palm of your hands. Being as it may, you need to select an air filter that you can be able to from one place to the other without straining. You might also want to consider one with handles, so you can easily lift it.

Noise levels

When shopping for an air purifier, it’s important to consider the noise levels. Most efficient air purifiers operate at between 20dB (low setting) and 50dB (high setting). For the sake of efficiency consider picking a unit that’s designed for the size of the room it is to be used.

Filter replacement indicator

Another very important factor to consider is the replacement indicator. This feature alerts you when your air filter needs servicing.


As with any electronic gadget, warranty is very important. Consider the time period that the warranty covers before it becomes void. Also, consider what the warranty covers such as electrical components, fan/motor, display, and other components. A good warranty period should not be less than 2 years.

Frequently Asked Questions

What is ACH?

ACH stands for Air Changes per Hour. It’s a rating that indicates the number of times in a span of one hour that the purifier can cycle air in a room.

How often should I run my air purifier?

The running period of your air purifier is highly dependent on a number of factors that include the make, model, and type of the purifier. However, it’s important to consult with the user manual. Most air purifiers come with a time-setting feature that lets you preset the number of hour/s that you would like it to run and then rest.

What is CADR?

Clean Air Delivery Rate or CADR is a numerical representation that indicates the volume of air processed by the filtration system and how effectively it’s freed of allergens.

What kind of air purifier do I need?

The kind of air purifier that you need is dependent on the type of contaminants you want to eradicate in your space. If you want to remove odors choose one with a carbon filter. To remove allergens such as spores and pet dander chose one with a HEPA filter. And to remove viruses and bacteria, consider one with an UV-C light.

Is it okay to open the windows when the air purifier is on?

No. To achieve maximum efficiency, an air purifier needs to be set up in a tightly sealed space. Opening the windows will also overwork the purifier.

As you can see, air purifiers are an important addition in your space. They are important for people who suffer from asthma attacks and other allergic conditions brought about by airborne pollutants. We hope that you will find an ideal air purifier for your space. Don’t forget to go through the above considerations before making a purchase.
