It can be quite a challenge to purchase just the best air purifier for a someone who is new to this field. The massive amount of products to choose from can be quite confusing, air purifiers come in all shapes, sizes and use entirely different technologies.

On top of that, there are even more equipment and accessories for air purifiers than you can imagine. Don`t worry, to ease your life I had done the hard part for you and wrote Best Air Purifier Buyers Guide.

In this buying guide, I will explain to you principal of must knows features of air purifiers. Everyone willing to buy air purifier should be aware essential features to look for as well what to run away from to buy the best air purifier for your needs.

Filter type


Of course, cleaning the air pollution requires a particular technology, and you can choose from five types of air cleaning technologies. The primary goal of all five cleaning technologies is the same – to filter the air of pollen, dust, odors, smoke and other pollutants that are dangerous to your health.

  • Electrostatic air cleaners
  • UV filtration
  • Mechanical filtering
  • Ion generators
  • Hybrid systems

The HEPA True is the most popular mechanical air filter, and it is very successful at cleaning air from pollution that can cause or even spread diseases. HEPA True air filters are extremely efficient at removing and capturing pollen, dust, pet dander and dust mites. The most important thing you need to remember when choosing an HEPA True model is to buy those who guarantee to remove 99.9% of air pollutants.

The ionic, electrostatic and UV filtration methods will be discussed in a separate article. But you should notice that the existence of a pre-filter increases purifier`s efficiency. Whether the filter is replaceable or washable, it prolongs the lifetime of your primary air filter. And if your pre-filter is made out of activated carbon then your air purifier will be much better at removing all kind of odors and smoke.

Air Change Rate

The ACH (air change per hour rate) indicates you exactly how many times the air purifier unit cleans all room air during one hour. If you had an air purifier that has ACH 6, it would clean all the air in room six times during one hour, or every ten minutes.
You must know that the advertised ACH rate usually means the maximum operating speed and the maximum room size. It is better to oversize air purifier by 20-40%, so the unit does not need to run at top speed to deal with air filtering. Also, it`s lifespan will be longer and it will work more quietly.

CADR Ratings

Clean air delivery rate (CADR) is also fully explained on a separate page. Clean air delivery rate is developed by home appliance air cleaner manufacturers. Its purpose is to help consumers understand how efficient and quick the air purifier you are willing to buy is. Efficiency will be calculated and rated by how many cubic feet of air the unit can filter just in one minute. There are separate numbers for three the most important categories – smoke, dust, and pollen.

The higher the number, the better. Air purifiers with higher CADR numbers will faster filter the air from pollution. It is very crucial to look for air cleaners with higher CADR ratings if you have large rooms that require constant air filtering. In case you can`t find an air purifier with sufficiently high CADR ratings, you can always move the air cleaner around the room to get equally fresh and clean air in all corners.
Room Size

When choosing the best air purifier, always take the size of your office or household and air purifier size into consideration to gain maximum air filtering efficiency. Air purifier models have various sizes starting from small, compact and portable up to quite significant models that take up a lot of space.
While room size is crucial, you also must think about how well the air will be filtered into the room, where you are going to use it. I might be repeating myself, but I always recommend to get a model that is made for operating in a slightly larger room than you have. That will guarantee that you always have fresh and clean air that is well filtered. Also, air purifier itself will live longer because it won`t run ar maximum capacity all the time.

Indicators and Sensor Technology

Indicators and sensor technology are both handy and crucial to improving air purifiers efficiency. As in many other industries also in air purifier industry manufacturers have taken next step and are using automated systems to improve the effectiveness dramatically. In best air purifiers it will mean automatical adjustment of fans speed, so if the air quality drops then, the purifier will automatically begin to filter it. It won`t work all the time, but only when needed.

Light indicators can save you time and money by telling when to clean or replace air purifier filters, so they won`t work until they are full of dust and become worthless. It also means that you will save money and won`t replace your filters prematurely.
