Best Air Purifier Reviews

It’s absolutely important that we breathe clean hair. However, this may not be the case for most of us. Due to the way that buildings have been constructed and the different things we bring into our homes, it is actually estimated that the inside of our houses is more polluted than outside. And since most of us spend the majority of our time indoors, this could pose a major issue for us down the line.

However, there’s no need to worry because the solution to this problem is rather simple. Air purifiers are able to remove up to 99.97 percent of these harmful toxins from the air, preventing you from breathing them into your lungs. This will help to make sure that the air you breathe is as clean as possible.

But with so many different brands available on the market, it might be difficult for you to decide which air purifier to purchase. In this buying guide, we will inform you about the different types of air purifiers, as well as some of the best options on the market according to customer reviews.

Different Types of Air Purifiers

Air purifiers come in many shapes and sizes, but they have 4 major types.

  • HEPA filtration: This is the most popular type and considered to be the gold standard. The paper filter traps contaminants and has the ability to remove 99.97 percent of all contaminants in the air, including ones that are only 0.3 microns in size. Make sure that the air purifier you’re purchasing has a True HEPA filter, because this is the most effective.
  • Ionic filtration: Ionic filtration works by releasing charged ions into the air, which then will settle onto contaminants. The contaminants then fall to surfaces, and the electrostatic plate in the purifier attracts the particles and gets rid of them.
  • Carbon filtration: These air filters have tiny absorbent pores, which have the ability to trap gases, odors, and fumes. They are not meant for removing any particles that cause health problems and allergies and are only able to remove those that cause smells.
  • UV light: This is a special technology that will release light to attack pollutants. It does not work as a normal filter and the UV light remains inside the purifier. It works by killing bacteria, viruses, and other pollutants by completely destroying their DNA.


Although there are certainly many air purifiers out there, some come from more popular brands than others. Here are some of the more popular brands on our list.

  • Hamilton Beach: Hamilton Beach is one of the most popular brands on the market when it comes to different appliances for your home. Some of the products this brand produces include air fryers, coffee makers, deep fryers, blenders, and more.
  • LEVOIT: LEVOIT is a brand committed to making products that are as environmentally friendly as possible and that do not emit ozone. They also produce humidifiers in addition to air purifiers.

Buying Guide

There are a few more factors to consider when you purchase an air purifier.

  • Get the right size: It’s crucial that you get an air purifier that is the right size. Make sure to check the square footage rating of the purifier that you want to get and see if it matches.
  • Check the CADR rating: This stands for Clean Air Delivery Rate and it measures dust, tobacco smoke, and pollen. The rating ranges between 100 and 450 and the higher the number, the better the device is at removing those pollutants.
  • Noise level: Many people place a lot of importance on how loud their air purifier is. This is especially due to the fact that people like to leave it on at night. Check to see how many decibels the air purifier operates at.
  • Timer: There are some air purifiers that allow you to set a timer for specific time intervals to ensure that it will turn off even when you’re not home or when you’re asleep.


Ensuring that the air you breathe is fresh and clean is one of the best things you can do for you and your family. This will help you to remain healthy for as long as possible, and if you or any of your loved ones have allergies, asthma, or other breathing problems, it can make a world of a difference when you purchase an air purifier.
