Air Purifier Buying Guide

Some people think of air purifiers as a luxury item—something only wealthy homeowners can afford. But what if I told you that an air purifier could actually save you money in the long run?

In this air purifier buying guide, we’ll explore the benefits of owning an air purifier and provide a buying guide to help you choose the right air purifier for your needs. So whether you’re a homeowner or a buyer, read on to learn more about air purifiers and how they can improve your quality of life.

Types of air purifiers

Air purifiers come in a variety of shapes and sizes, but they all serve the same basic purpose: to remove pollutants from the air. Here are the four common types of air purifiers you will find in the market these days:

  1. HEPA Filter Air Purifier

A HEPA filter air purifier is a powerful tool to help improve the quality of the air in your home. HEPA stands for high-efficiency particulate air, and HEPA filters are able to remove 99.97% of airborne particles that are 0.3 microns or larger.

This includes dust, pollen, smoke, and pet dander. By running a HEPA filter air purifier in your home, you can enjoy fresher, cleaner air and may even notice improved respiratory health. Additionally, HEPA filters can help to reduce odors from cooking, smoking, and pets.

If you’re looking for ways to improve the air quality in your home, a HEPA filter air purifier is a great option to consider.

  1. Activated Carbon Air Purifier

Activated carbon filters are one of the most effective ways to remove airborne contaminants from your home. The carbon filters help to adsorb particles like pollen, dust, and smoke from the air, trapping them on the surface of the filter.

This prevents them from being recirculated back into the air, leaving you with cleaner, healthier air to breathe. In addition, carbon filters are also effective at removing volatile organic compounds (VOCs) and other harmful chemicals from the air.

As a result, an activated carbon air purifier can help to improve your indoor air quality, making it safer and more comfortable for you and your family.

  1. Ultraviolet Air Purifier

One type of air purifier that is becoming increasingly popular is the ultraviolet air purifier. These devices use ultraviolet light to kill bacteria and other contaminants in the air.

Ultraviolet light is safe for humans and animals, and it does not produce any ozone or other harmful emissions. Additionally, ultraviolet air purifiers have a high clean air delivery rate, meaning they are very effective at improving indoor air quality.

If you are concerned about the air quality in your home, an ultraviolet air purifier may be a good option for you.

  1. Negative Ion Air Purifier

Most of us are familiar with the feeling of fresh air; it’s invigorating and energizing. Now there’s a way to enjoy that feeling indoors as well: negative ion air purifiers.

These devices work by releasing negative ions into the air, which then bind to airborne particles like dust, pollen, and smoke. The result is cleaner, fresher air that can help to improve respiratory health and boost overall well-being.

In addition, negative ion air purifiers can also help to reduce static electricity and eliminate odours. So if you’re looking for a way to enjoy fresh, clean air indoors, consider a negative ion air purifier.

How to determine the size of air purifier you need

With so many different air purifiers on the market, how can you be sure you’re choosing the right one? One important factor to consider is the size of the unit.

The rule of thumb is that you should choose an air purifier that covers at least twice the square footage of the room you’re using it in. For example, if you’re looking for an air purifier for a small bedroom, a unit that covers 100 square feet would be a good choice. Another factor to keep in mind is the specific needs of your home.

If you have pets or live in an area with high levels of traffic pollution, you may need to choose a unit with higher CADR ratings. By taking these factors into account, you can be sure you’re choosing an air purifier that will provide the fresh, clean air that your home needs.

Mechanical vs Electronic Filters

Most air purifiers use either mechanical or electronic filters to remove contaminants from the air. Mechanical filters work by trapping particles on a filter media, while electronic filters use an ionization process to charge particles so that they are drawn to a collecting plate.

Both types of filters are effective at removing a variety of airborne contaminants, but there are some key differences between them. Electronic filters are more effective at capturing smaller particles, while mechanical filters have a longer lifespan and are better at capturing larger particles.

Ultimately, the best type of filter for an air purifier depends on the specific needs of the user.

Price points for various types of air purifiers

Air purifiers come in a wide range of prices, depending on the features and type of purifier. The most basic air purifiers can cost as little as $30, while more advanced models can cost over $300. The type of air purifier you need will also affect the price.

For example, HEPA filters are more expensive than activated carbon air purifiers. Additionally, air purifiers with multiple filters will typically be more expensive than those with only one type of filter. Ultimately, the best air purifier for you is the one that fits your budget and meets your needs.

Brands to consider when purchasing an air purifier

Air purifiers are increasingly popular as people look for ways to improve the air quality in their homes. However, with so many different brands and models on the market, it can be tough to know which one to choose. Some factors to consider include the size of the unit, the features offered, and the price. Some of the most popular brands include Blueair, Honeywell, and LEVOIT.


Blueair units are available in a range of sizes to suit different needs, and they offer both HEPA and activated carbon filters for maximum effect.


Honeywell units are also available in a variety of sizes, and they offer both mechanical and electronic filters.


Finally, LEVOIT units boast a high CADR rating and an affordable price tag. Ultimately, the best brand for you will depend on your specific needs and budget.
