Factors That Influence Your Buying Decision

If you plan on buying air purifiers from an actual store, watch out! The salespeople there are notorious for attempting to confuse you with a lot of technical talk. Here are some of the most common terms you need to know, along with a brief explanation of the different types of purifiers and filters. The more knowledge you have, the better you will be able to make a more informed, wise decision as to the purifier you need.

First off, you need to think about the CADR or the clean air delivery rate. This is, as the name suggests, the rate at which the device cleans the air it takes in and pushes it out into the room that is being purified. This includes getting rid of all those nasty allergens and toxins. Typically, three toxic substances are cleaned out – smoke, dust, and pollen. Each has its own rating for the CADR, which depends largely on the size of the filter being used as well as the type.

The flow rate of the purifier is simply the rate at which air flows through it over time. All purifiers have fans that suck in air and blow it out again. The more powerful the fan, the higher the flow rate. Another factor that affects this value is the type of the filter cleaning up the air. A larger filter means more surface area, which leads to a higher flow rate!

Other factors that should affect your buying decision for air purifiers include the size of the device, the type of filter it uses, the technology within these filters and additional features that make your life easier. Some purifiers also clean out specific types of germs and toxins with a higher priority given to these.

Taking these factors into consideration, here is a list of the ten most awesome air purifiers for 2017, consolidated and reviewed especially for you. While they are definitely not the only options open to you, they are some of the best out there. If you don’t think any of these suit your needs, the world of purifiers has more to offer. Check out the detailed instructions on what to look for in the perfect filter under the top ten air purifier reviews below!

Factors to Watch for When Buying Purifiers

There are many different factors that should influence your buying decision if you go to a store to buy yourself an air purifier. These include:

1. Filter Type​

    1. Mechanical filters – the HEPA filter is the most common of these. They work by physically stopping particles from flowing through using a grid of fiber. All the HEPA filters in our top ten are of the True variety, which can remove 99.97% of particles.
    2. Ionic filters – They make small particles in the air bond with each other and become larger. These can be trapped far more easily.
    3. UV filters – expose bacteria, viruses, and germs to UV radiation which kills them and takes away their ability to reproduce.
    4. Electrostatic cleaners – A charged rod that attracts particles to it like a balloon rubbed on a woolen cloth attracts bits of paper.
    5. Hybrid systems – a combination of two or more of the other types of filters.

2. Air Change


This value is the number of times the purifier will clean all the air in the room per hour. For example, if it is 5, the device replaces all the air in the room 5 times each hour. This is at maximum speed, though, so try to get a purifier with a higher rating than you need, so you can enjoy quietness while cleaning.


3. Size

Think about how large your room, house or office space is, and consider space savings when you pick a purifier to fit it. For example, the Whirlpool model on our list would not be great in a small bathroom or bedroom.

When picking a model out though, ensure that it can service a room that is slightly larger than you need it to be. This ensures that your operation of the purifier will be free of background noise and will put less strain on the system.


4. Sensors, Automation, and Notifications

This feature, when present, improves your quality of life but doesn’t impact how well the purifier functions directly. Most new models have automatic notifications for when the air filters need to be cleaned or replaced. Others detect the quality of air in a room and change the fan speed accordingly to keep it at a set level of purity at all times.

Other models can function as nightlights that can turn on when it is after sunset. Sensors and indicators are a great way to save some money on energy bills and replacement parts.

Final Words

So, there you have it! The best ways to either pick out air purifiers of your own, laid out in crisp, easy detail for you. Remember that no two filters and purifiers are the same. Some may be better suited to your specific needs; others may not.

Think about the factors like sizing, filter types and indicators before you make a hasty buying decision. It is the only way you can ensure that your air is cleaned, purified and made easier to breathe without costing you most of your savings. When buying, don’t get distracted by fancy advertising. Here’s to your fresher, more incredible life with truly pure air in your lungs!
