What is an Air Purifier

The problem of air pollution is very acute nowadays because human health is influenced by street dust, car exhaust gas and other harmful contaminants. Such devices as air purifiers were invented to protect people not only from the negative impact of the above components but also from pet dander, harmful bacteria, pollen, fungi and various residential odors. air purifier systems operate in a simple way - they consist of a set of filters that provide various degrees of cleaning and a fan which pulls in air for cleaning.

Consumers should keep in mind that residential air purifiers neither drain nor humidify the air. For these purposes, it is advisable to consider an air humidifier or air washer.

What Features to Compare

Filters and Filtered substances

If you’ve made your mind to buy an air purifier, it’s important to consider filters and filtered substances, and find out if the chosen unit is going to be effective for your place. Most expensive, high-quality air purifiers feature a 3-stage filtration system with three layers of filters.

HEPA-filter is a special filter, allowing to remove up to 99.97 particles and pet dander from the air. These air filters will cater to the needs of allergy customers. They are extremely efficient and cost-effective. HEPA filters are usually washable and replaceable which not only reduces replacement costs but also significantly extends the lifetime of a filter itself.

Filters of activated carbon are produced for those who can’t stand foreign smells in their houses. These filters will not only purify the air, but also absorb tobacco, food and pet odors with ease. You can also consider air filters of activated carbon and baking soda, allowing for even more effective purification.

You can also find air purifiers with UV lights, which are extremely effective at killing harmful germs, allergens, viruses and bacteria. Such air purifier can become the best disinfector in your place. It does effective cleaning and it’s very durable.

A lot of consumers give preference to air purifiers with functionality of a humidifier. They are designed to maintain the right humidity level in the room as well as purify the air from polluting particles and absorb unpleasant smells.

Coverage Area and Noise Level

Each air purifier has got its own coverage area. You can’t expect a device with a small coverage area to be effective in a big living-room, so be aware. However, if your room is of a moderate size, you can opt for a more compact, portable purifier.

Another aspect to take into account is the noise level each air purifier creates during operation. A lot of consumers use air purifiers in their bedrooms to relax and have good sleep at night, thus quiet operation at high speeds is required. The noise range of 15-30 bD is optimal and amounts to the sound of falling leaves. 35-45 dB is equal to the sounding of normal conversation. The units that create over 50 dB of noise are not recommended for use in the nighttime.

Control and Functionality

All air purifiers feature their own functionality and controls. Several speed settings allow consumers to set the right one for their needs. Most air purifiers have also got timers, indicators to alert on filter replacement, automatic air purification system control and so on. The choice is vast so that everyone can find the best pick.

Smart Control

It's got three color lights indicating different levels, from red, orange to green with the latter being a favorable air condition indicator respectively.

We'd recommend you to stick to average rating. But when the viruses spread in public and there's a big risk to catch a cold, that's the time for you to crank it up to the full extend. Make sure to replace filters on time, otherwise using air purifier won't give any effect.
