Buying Guide

What is an Air Purifier?

An air purifier is a device that helps to eliminate air contaminants or pollutants present in a particular area. This device helps to improve the quality of the air in the surrounding area.

Some indoor pollutants such as dust, chemicals, smoke, pollen, pet dander, and odors need to be gotten rid of to allow fresh air. According to research, indoor air is more polluted than outdoor air.

How does an Air Purifier Function?

There are two main components in an air purifier: the fan and filter. The filter in this device can be single or multiple, depending on the type of brand you choose. The fan sucks the air inside and dispenses it out. At this point, the contaminants and impurities are eliminated, and the clean air will circulate in the surroundings.

The filters in air purifiers are made of materials such as paper, mesh, or fiber. Regardless of the filter type, regular and proper cleaning should be done to maintain good performance and efficiency. Therefore, it is important to consider the cost of maintenance before purchasing an air purifier.

Features to Consider when Choosing an Air Purifier

When choosing an air purifier for your home or office, you need to consider some important features. Choosing the best air purifier can be quite frustrating since there are a lot of brands available. We will be discussing the important features you should look out for in an air purifier.

Type of Air purifier

There are different types of air purifiers and the one you choose depends on where you intend to use it. Some people need this device in a single room while others need it for the entire house. Air purifiers come in three different types which are portable air purifiers, whole-house air purifiers, and commercial air purifiers. Each of these air purifiers serves different purposes.

The portable air purifier is also known as room air purifier. It works well for single rooms like bedroom, kitchen, bathroom, etc. This type has no heating or cooling system, making it transportable. You can turn this purifier on when people are in the room. The whole-house air purifier is a perfect option for people who look forward to purifying the entire house. This purifier can be connected to an existing heating system.

This type of purifier is super efficient as it can improve air quality within a few seconds.  The whole-house air purifier features durable filters and doesn’t require much maintenance. The commercial air-purifier is ideal for large areas like halls, warehouses, offices, lounges, malls, etc. This type can get rid of 99 percent of pollutants in large spaces.

Room size

This is another important feature you need to consider. Since different types of air purifiers can suit your needs, it is very important you pay attention to the size of the room you intend to place it. Check the room space to know if the air purifier is capable enough.

 If you want to be certain, you can calculate the room size by measuring the width and length of the room, and then multiply to get the result. For multiple rooms such as the kitchen, bedroom, and living room, you will need to add up the area of all rooms to determine the total capacity you need.


You can improve the result you get from an air purifier by placing it in an appropriate place. Ensure you position the air purifier where there is enough space around to avoid anything interfering with airflow. Placing the air purifier against any obstacle can reduce the level of its performance. Place an air purifier about 7 feet far from the headboard when using one in the bedroom.

Air purifiers featuring HEPA or carbon filters utilize fans to suck air in and out. Such air purifiers should be placed 2 to 3 feet away from furniture or wall. Avoid placing them behind the couch or under the bed, this can reduce performance. Air purifiers with ionic filtration are best placed in the center of the bedroom.

Energy consumption

Air purifiers are powered by electricity and as such, need a constant supply of electricity to function. Therefore, if you are considering how much you will be charged for electricity bills, it is advised you do a proper calculation to know how much energy is consumed by an air purifier.

Most air purifiers available in India use up between 50 watts and 200 watts. To know the amount of power consumed by an air purifier, you can look out for the energy star rating before purchasing.

Filter Replacement

Apart from upfront costs, there are some costs you incur on the replacement or maintenance of the filter. Some models come with two different types of filters, in such cases; you will need to get each of them replaced individually at different time zones. The usage and air quality determine the lifespan of a filter. Carbon and HEPA filters need to be replaced often since they won’t function well if clogged up.

If your air purifier comes with any of these filters, it is important you check out the manufacturer’s instruction on the duration of filter replacement. Usually, it takes 3 months to 1 year to have them replaced. However, the ionic filter is the best as it is cost-effective.

Noise levels

Air purifiers make a noise, however, the noise level varies, depending on the fan’s speed. Purifiers having HEPA or carbon filters require fans to function well. Most of these fans feature two-level speed; high and low. Some high- performance models feature 5-speed levels such as high, low, medium, automatic, and turbo.

If you intend to place the purifier in the bedroom, ensure you get a brand that doesn’t make too much noise.


This is a very important feature you need to consider. Different brands offer different warranty periods. The duration of the warranty provided by a brand is a good indicator of how efficient the products are. Some air purifier brands offer a 1-year warranty while some offer up to a 5-year warranty.

It is advisable to go for brands that offer warranty for parts, this will enable you to get some parts replaced or repaired when damages occur. Popular brands are known to offer long-term warranty for their products.

Other features

To make things much easier, some brands provide other features. These features can add up to the cost of an air purifier. Other features like programmable timer, digital controls, antimicrobial treatment, casters, plasma-wave technology, air quality sensor, a nightlight, fan speed, and programmable timer are provided by high-end brands.


Overall, your budget determines the type of brand you buy. Air purifiers are available at various prices. Sometimes, the price of an air purifier reflects its quality. There are high-performance brands that offer additional features like remote control, digital control, pre-filter, filter replacement indicator, and carrying handle among others.
