Checklist of the Best Air Purifiers Features to Consider

Feature Consideration #1 - Filter Type

The first thing you need to consider when reviewing an air purifier is what type of filter (or technology) it uses to purify the air. This makes a huge difference in which product is the best air purifier for your needs.

Imagine this scenario…

You have asthma and want a device that will clean the air of harmful asthma triggering particles. So, you choose the cheapest unit you could find that had great air purifier reviews. You bring it home, plug it in and within a few hours you feel your asthma getting worse. How can this be? The air purifier was supposed to help you feel better not trigger more asthma attacks!

You see, in this situation the air purifier used a technology called an “Ionic Generator.” Many times this device also goes by the name “Ionizer” or just “Ionic air purifier.”

Ionic devices purify the air by sending out negative ions into the air that attach onto positively charged particles (pollen, bacteria, mold spores, etc.). Eventually, too many negative ions latch on to the particle, cause it to become heavy and fall to the floor. However, these negative ions are bad for people with asthma. This type of air purifier actually causes your asthmatic symptoms to get worse!

Knowing this little bit of information would not only saved you time and money, but also kept you in better health. Instead, if you have asthma you want an air purifier that does not use any type of particle generation, but rather a physical filter that traps any and all particles floating in the air. The best air purifiers that fit this category are HEPA devices.

If you don’t have asthma problems, feel free to get an Ionizer, because these units are usually the cheapest option.

A HEPA air purifier is the perfect choice for someone with asthma and/or allergies. This type of unit sucks in the air from all around the room into a physical filter. They are guaranteed to remove 99.97% of particles that are 0.3 microns in size. This includes allergy and asthma triggers such as pollen, mold spores and some bacteria.

If you want the best type of air purifier that truly cleanses the air to the fullest, be sure to get a device that uses this filter type.

The only drawback to these units are that they tend to be more expensive than Ionizers. But, usually not by much.

When buying an air purifier and reading air purifier reviews also take into consideration getting a device that has an Activated Carbon Pre-Filter. This filter is essential if you want to remove nasty odors or smells from your house. You see, neither a HEPA filter nor an Ionic purifier alone do any good to remove odors. They just are not built that way.

Instead, a Carbon Filter is equipped with absorbent material that actually soaks up any smells produced by smoke, chemicals or gases. Make sure the device you get has this if you want the freshest, cleanest, smelling home or office.

The final type of air purifier technology you’ll come across when looking for the best air purifier for your needs is called Ultra Violet or UV filtering. What this means is that the device sends out a beam of light that radiates throughout the room and can actually kill viruses and bacteria. It does this by destroying its DNA structure. No other air purifier can do such a thing and in fact you must have a UV light equipped unit if you want to remove harmful particles that make you sick. This type of device is perfect for those of you who have low immune systems, get sick often or just want the most sterile environment possible without turning your house into a hospital!

Feature Consideration #2 - ACH Rating

Another feature you’ll come across when researching the best air purifiers is called the ACH rating, or Air Changes Per Hour.

To keep this short, it simply tells you how many times a device will filter the air within a room each hour. The higher the number the cleaner the air space. Never get a purifier that has less than a 4x rating. This is the minimum standard you should consider when reading air purifier reviews and finding the best one for your house or business.

Feature Consideration #3 - CADR Rating

Another important feature to understand is the CADR rating, or Clean Air Deliver Rate. This rating is essential to look at when comparing two purifiers that may otherwise seem to be the same.

As with the ACH rating, the higher the number the better. In fact, the CADR rating includes three numbers and looks like this 220/180/230, which stand for how well the unit purifies the air of Dust, Pollen and Tobacco Smoke.

An air purifier with a CADR rating of 200/200/200 is obviously better than one that has a 180/180/180 rating (with all else being the same).

So, try to find the highest rating possible within the budget range you have to spend on a device.

Other Things to Consider

A few other things you should consider when looking for the best air purifier are: Room Area Coverage, Energy Star rating and Price.

The Room Area Coverage tells you how big of a room the air purifier can clean. This is expressed in square feet, for example 150 sq. ft. Make sure you choose a unit that can filter equally or more than the space you are going to put it in. For example, if your living room is 180 sq. ft, you need an air purifier that has a Room Area Coverage specification of at least 180 sq. ft. such as one with 200 sq. ft. An device that is only rated to purify a space as large as 130 sq. ft, won’t cut it. If you buy that unit you are wasting your money because it will be inefficient.

The Energy Star rating is simple to understand. Always look for a device that has this certification. This ensures that it operates at the lowest energy cost, saving you money on your electric bill!

And finally, compare prices! You never a want to spend more on an air purifier than you can afford. Also, keep in mind the cost for filter replacements. Every HEPA air purifier must have its filters replaced in order to be effective. They get clogged from continuous use. Factor these costs into your budget. If you don’t have asthma, you might want to consider getting an Ionic air purifier, because these devices do not require filter changes. Instead, they have a collection plate that collects the particles onto and these are washable and reusable for the life of the unit.

We’ll, we hope these tips helped you be able to better sort through the best air purifiers for your home or business. Since you read this far, you should feel good about yourself because you now know 90% more than most other consumers who are looking to buy the same thing!
