Types of air purifiers

There are mainly five different types of air purifiers that you need to know about.

  1. HEPA purifiers

This technology has been here for quite a while now. Mainly used for purifying the air indoors, HEPA air purifiers are a common item on a household scale. Standing for High-efficiency particulate air, it is designed to filter microscopic particles.

  • Adsorbent purifiers

Adsorbent purifiers are made of activated charcoal and they trap odors and chemicals that are floating around in the area. Adsorbent air purifiers are also often used in environmental cleanup attempts because they act like a sponge, taking up the toxic substances.

  • UV purifiers

As the name suggests, UV purifiers work with the rays from the sun to kill the microbes. UV purifiers work in a similar way to the destruction of DNA and RNA in the skin that can then lead to cancer. These purifiers work similarly but kill microbes.

  • Iconic purifiers

Iconic purifiers provide a filter less exchange to HEPA air purifiers. Iconic purifiers produce ozone, so there have been concerns raised about the damage to the ozone.

  • Ozone generators

Finally on the list of air purifiers is an ozone generator. The idea of “ozone” being in the name, suggests that it is not recommended to be used for indoor purposes. Nevertheless, it is believed that they are important for other purposes.

Now that we have looked at some of the types of air purifiers, let us see what we need to look for. There are a few important things that you need to look for in an air purifier.

  1. Effectiveness

An air purifier can have variable effectiveness based on the model. Effectiveness deals with the ability to remove the number of airborne particles from the air, hence cleaning it.  While a low-end air purifier removes 30% of particles, a higher quality one may be able to remove up to 99.97%. Hence, when buying an air purifier, the effectiveness of the device is important.

  • Features of the air purifiers

When finding which air purifier to buy, you need to consider several features like the shut-off timer, the indicator for filter life, sensors for air pollutants, etc. Features are an important aspect of finding the right air purifier.

  • Style of the device

While the functioning of the purifier is greatly important, you might want to get one that matches your style. In simple words, you may want to consider how well the air purifier fits with your home décor.

  • Square footage/area

The effectiveness of the purifier will be affected by the placement of the device. Before buying your air purifier, consider where you will be placing it, along with the square footage that will be covered by it.

  • Warranty of the product

Warranty is one more thing that you wouldn’t want to miss out especially if you are planning to use your air purifier for the long-term. When talking about air purifiers, one thing to remember is that the shorter the warranty of your product, the shorter its lifespan will be. Hence, you may want to get an air purifier with a longer warranty.

  • Price point/Price range

The most important thing that counts at the end of the day, is the price of the air purifier. An air purifier is like an investment for your health. While some brands claim good results at a lower price, our experience says that the quality does vary with the price. Hence, it is recommended to make a good one-time investment in a good air purifier.
