Air purifiers are a great way to improve the quality of the air in your home, and they can help reduce asthma and allergy symptoms. But not all air purifiers are created equal. There are a lot of different options on the market, and it can be difficult to decide which one is right for you. That’s why we put together this guide – to help make the process easier for you!

Air purifiers

Air purifiers can remove many different types of dust and pollen from your home.

Air purifiers are devices that clean the air in your home by removing allergens, viruses, fungal spores, dust, bacteria, pollen, and airborne chemicals. Air purifiers come in a variety of sizes and styles, so it’s important to do your research before buying one to make sure you choose the right one for your needs.

The benefits of air purifiers

Using air purifiers can help people suffering from allergies.

There are many benefits to using an air purifier in your home. For example, air purifiers help reduce the amount of dust in the air, which is beneficial for people with allergies or asthma. With cleaner air to breathe, you’ll be able to breathe easier and feel more comfortable in your own home.

Now that you know what an air purifier is and what the benefits are, let’s dive in and discuss the 9 key points you should know before you purchase an air purifier.

1. How do you know if you need an air purifier

If you have allergies or asthma, an air purifier can help to improve your quality of life by removing particles from the air that can trigger your symptoms. If you don’t have allergies or asthma but are still interested in purchasing an air purifier, there are a few other factors to consider. Pollution, pets, and cigarette smoke can all contribute to poor indoor air quality. If you’re concerned about any of these things, an air purifier may be right for you.

2. Not all filters are equal: HEPA filters can remove 99%+ particles 

If you suffer from allergies, asthma, or other respiratory ailments – especially if they are triggered by visible particulates like dust mites and pollen- the right type of air purifier could be just what your doctor ordered. HEPA (High-Efficiency Particulate Air) filters can remove 99%+ particles that measure 0.3 microns in diameter (as measured on industry standards) so it will help keep them at bay! Not all units meet this high standard though, so be sure to check before purchasing.

3. Air purifies and COVID-19

Recently, people often ask whether air purifiers can protect against COVID-19. Well, we are in no position to answer this, it’s best to seek proper medical advice with respect to vaccines, mask-wearing, and other protective measures. However, air purifiers with a HEPA filter can capture particulate matter the size of airborne viruses, including COVID-19.

4. The importance of CADR

If you want to buy an air purifier, you should research the CADR of each air purifier.

It’s also important to consider third-party certifications when making your purchase. Air purifiers that have a Clean Air Delivery Rate (CADR) rating have been tested by an independent laboratory.

The amount of air purified by a purifier at a given time is called the “CADR”. This stands for Clean Air Delivery Rate and it is usually expressed in cubic feet per minute (or m³/h). Want to figure out the required CADR for a particular size room? Use this CADR calculator.

5. How often should I change the filter in my air purifier?

The frequency at which you’ll need to replace the filter in your air purifier depends on the type of machine you own and the type of filter it uses. Some filters need to be replaced every few months, while others can last up to a year. Be sure to check the manufacturer’s instructions for your specific model.

Filters do most of the dirty work inside an air purifier and they require regular attention. Whether made of paper, fiber, or mesh; the filters can usually be cleaned or replaced every few months (check your owner’s manual for specific recommendations). Some filters are reusable but they need meticulous maintenance so you don’t tend to find many of these types of models.

6. Where should I place my air purifier in my home?

The best location to place your air purifier is normally near a window or close to a doorway. You want to put the purifier close to moving air and that’s because moving energy is able to move around dust and other pollutants.  

7. What size air purifier should I buy? 

If you want to buy an air purifier, it's a good idea to do market comparisons.

Air purifiers come in a variety of sizes, so it’s important to choose one that is right for your needs. If you live in a small apartment, you’ll need a smaller air purifier than someone who lives in a large house. The good news is that you can expect each air purifier to specifically state the area they cover. For example, some air purifiers will be good for rooms up to 200 square feet whereas others, may be suitable for rooms between 200 and 400 square feet. You can even buy air purifiers for use in the car!

8. Market product comparison

When you’re shopping for an air purifier, it’s important to compare different products. Air purifiers can vary in price and features, so be sure to do your research before making a purchase. Some of the factors you may want to consider include filter type, size, noise level, and technology.

You can also find air purifiers that are Energy Star certified, which means they meet the standards for energy efficiency. Also, make sure to read reviews before purchasing an air purifier, as this can help you make a more informed decision.

9. The air purifier we use

We personally like the Amway air purifier which comes in three different sizes. We use the Atmosphere Sky™ Air Treatment System which is suitable for rooms up to 465 square feet. This air purifier is certified by Allergy UK in all 22 trigger categories and is the only air treatment system that has been certified by Allergy UK that effectively reduces 102 types of allergens in the air – this makes it a great option for allergy-prone people.  


When shopping for an air purifier, be sure to read the reviews and compare different models. Air purifiers can vary greatly, so take the time to find the right one. If you want to get more advice on choosing air purifiers, feel free to contact Terry for help.
