Finding a High-Quality Air Purifier: A Buyer’s Guide

While living in a metropolitan city comes with tons of benefits, including the food, the architecture, and the people, there’s also the concern of air pollution and inhaling harmful chemicals every day. The emissions from vehicles alone are enough to put plenty of harmful chemicals into the air, making it unhealthier to breathe. Some effects of air pollution are more immediate, like allergies, throat irritation, and nausea, while others, like increased risk of asthma or chronic lung diseases, take more time to surface. Fortunately, you can help minimize these effects by using a quality air purifier inside your home and maintaining a healthier, fresher environment. These purifiers not only help remove harmful chemicals from the air, but they can also remove unpleasant odors, reduce dust particles, and help improve the overall air quality. We’ve rated and reviewed some of the finest air purifiers for 2023 to help ensure your family breathes fresher healthier air.

Because of their recent rise in popularity, the market for air purifiers has been flooded with hundreds of models. Check out this detailed buyer’s guide for some tips and things to look for when searching for the right air purifier for your specific needs.

Choosing a Quality Air Purifier

Size and coverage

Air purifiers come in many different shapes and sizes, from smaller models that plug into the wall to larger versions that can clean the air in a whole house. When choosing an air purifier, you should think about the rooms you want to clean the air in — or you can go for a portable unit that you can use all over your house. Once you have the measurements of your area, you can choose an air purifier that takes up the right amount of space.

Filtration system

Most high-quality air purifiers have three or five-stage filtration systems that can get rid of all kinds of air pollutants. We recommend getting an air purifier with at least a pre-filter, a HEPA filter, and a carbon filter for the right amount of air filtration. The pre-filter gets rid of bigger, more obvious pollutants that can hurt the fine-filtration layers inside. The air then goes through a HEPA filter, which catches the smaller particles. Last, the carbon filter soaks up the gaseous molecules that can cause different smells to linger in a room.

Air change per hour (ACH)

ACH is the number of times in an hour that an air purifier can clean and change all of the air in a room. The higher this number is, the more efficient an air purifier is. Try to get an air purifier that can change the air at least four times an hour.

Clean air delivery rate (CADR)

CADR is the amount of air that an air purifier can clean at its highest speed. The rate of cleaning the air is faster when the CADR is higher.

Noise level

You should know that an air purifier can be a loud household appliance. While the noise won’t bother you much during the day, it can keep you from sleeping well at night.  So, if you want to use an air purifier at night, make sure to get one that doesn’t make a lot of noise. Look for a model that has a sleep mode or makes a noise at less than 40 decibels.

Getting the Most From Your Air Purifier

Here are a few tips to help you get the most out of your air purifier:
  • To keep your air purifier working well, you should clean or replace its filters often.
  • Put the unit in a room where you spend most of your time, or that is in the middle of your home, for better results.
  • Set up the air purifier so that nothing restricts its airflow.
  • Run your machine at full speed when a room is empty and at a lower speed when people are in it.

People Also Asked

How can I judge the efficiency of my air purifier?

The filtration system of an air purifier determines its efficiency, so always go for a multi-stage filtration system for cleaning indoor air. It’s better to get a unit that has at least a three-stage filtration system, including a pre-filter, a HEPA filter, and an activated carbon filter. Air purifiers with five-stage filtration systems, on the other hand, are even more efficient.

Why should I use an air purifier?

An air purifier, as the name suggests, filters the air by trapping harmful pollutants like dust particles, smoke, mold spores, pet hair, and pollen — and they can help get rid of bad odors, too. Some air purifiers also come with an aromatherapy design, so you can freshen up your indoor environment as well help purify it.

Can my HEPA air purifier trap and remove coronavirus?

With the outbreak of the pandemic, some manufacturers have upgraded the designs of their air purifiers to capture the droplets that can spread coronaviruses and COVID-19. Make sure to confirm this with the manufacturer before relying on a product though.
