8 Pointers to Consider Before You Buy Air Purifiers

Indoor air contains more pollutants than the outdoor air. Due to lack of awareness, most people don’t care about the quality of air in their houses. Indoor air pollution consists of a lot of elements, such as pet hair, stoves, fireplaces, paints, varnishes, dust mites, bacteria, mold, mildew and smoke, to name a few. An easy way to purify your indoor air is to go for an air purifier.

In this article, we are going to share with you a few important pointers that can help you buy the right unit.

Cost of Maintenance

Your air purifier will work properly only if you maintain it properly. Make sure you have a clear idea of what you will have to do to ensure your device works properly.

Filter Replacement

Also, if you are planning to go for a HEPA air purifier, make sure you know the replacement cost as well. Generally, the life of the filter depends upon a lot of factors, such as usage and air quality.

As a general rule, the lifespan of a good HEPA filter is around 2000 hours. So, you may need to replace the filter after 6 months or so.

Automatic Monitoring

Find out whether the unit features an automatic monitoring system. This feature allows the unit to detect the level of pollution in the room. Aside from this, these units have infrared detectors that allow you to adjust the speed of the unit.

The Level of Noise

You don’t want a device that makes a lot of noise when working. Therefore, it’s important to go for a unit that can maintain minimum level of noise. For low noise and better efficiency, you should go for a big unit and operate it at a lower speed.

Power Consumption

Just like other appliances, air purifiers require power to work. Since these devices are run for hours non-stop, make sure you invest in a unit that doesn’t consume a lot of energy. Generally, most of these units consume between 50 and 200 watts in order to work properly. In other words, it’s better to buy a unit that consumes the least amount of power.

Reputation of the Maker

Before you buy an air purifier, make sure that you consider the manufacturer reputation as well. Aside from this, you can read the reviews left by the customers of the product before making your ultimate decision.

You should buy from a manufacturer that enjoys great reputation and offers top quality products.


If you want to purchase a good unit, make sure you go for one that comes with warranty. This is important to prevent a lot of issues down the road. Before you go for a product, you should try to get a better idea of the components of the unit like fan, motor or other parts. These components should be covered under the given warranty.

After-Sales Service

Another important thing is to check the installation and post-demonstration services offered by the maker in your area. You should contact the manufacturer to find out more about their after-sale service. Ideally, they should offer prompt post-sales service. This will help you deal with the issues that may arise after you have bought the unit.

In short, you should consider these pointers when buying a good unit.
