Filtration work

HEPA filters are the most popular and effective for air cleaners. They were made to suck allergens, mold or dust in and after free a clean air. Such filters can collect up to 99.9% of impurities, which make the air quite dangerous. As a result, you can get hay fever or asthma. Therefore, filtration work is very important, and it should be excellent.

Air flow

When it comes to a flow of the air, it has to be continuous. You must be able to choose the speed (it can depend on a type of a filter). What else you should notice is how many times the volume of the air replaces. Surely, the highest number you opt per hour, the better for your health. Do not forget that you have to regard the size of your house or apartment.


Clean Air Delivery Rate relates to a filter in an air purifier and shows a capability for cleaning smoke, dust and pollen. CADR corresponds with a specific type of a filter and its size inside an air cleaner.

What Function You Want the Air Purifier to Fulfil

Now, take a minute to think well about what you really expect from your air purifier, and what is the initial reason for you buying one? Are you someone susceptible to allergies that may be easily triggered by different particles floating in the air? Is it hair or pet dander that are causing you so much trouble? Are the airborne bacteria and virulent viruses that have made you look for a powerful air purifier? Would you like to completely get rid of the tough smoke seeping into the walls of your house? Are you dreaming about removing all the unpleasant odors that appear in your dwelling for whatever reasons? Or maybe you are simply looking for a way to boost the level of overall health in your family and reduce the risks of various unpleasant diseases?

Choosing the Air Purifier Technology and Filter Type in Accordance with Your Needs

After you have decided for yourself what functions you want your future air purifier to perform, you can use this knowledge for choosing the air filter technology that would suit your needs and solve your specific problems.

It is not hard to guess that there exist different air filtering systems dedicated to purifying the air from particular kinds of air pollutants more efficiently than the others.

Do not worry: it is not necessary to go deep into the complicated technical details of the way each filtering system works so that to be able to choose the one you need. We will make this part of your searches for the best air purifier as easy as we only. Namely, we will explain in layman’s terms only those features that you are advised to know and understand to make a deliberate decision.

True HEPA Filter

This is a physical-type filter characterized by high efficiency of performance. If you have come across a really good air purifier, it most likely contains this type of filtering technology.

What you need to be especially careful about is whether the characteristics of a certain air purifier include the phrase “true HEPA”, which means an authentic HEPA filtering system, instead of the “HEPA-type”. An authentic, or true HEPA filter has a certificate proving its capability to eliminate 99.7% of all contaminative particles having the size of up to 0.3 microns. In comparison, filtering systems positioned as “HEPA-type filters” can get rid of the polluting particles as small as 2—3 microns. For you to understand this difference more vividly, look at your hair — it is around 2 microns thick.


prosEffectively eliminates different types of allergens including dust particles and dust mites, mold spores, pollen grains, etc.

prosThe pollutants cannot escape back in the air that has been purified with this device


Minus_Circle_Green Cannot fight various smells and odors, smoke, and chemical fumes

Minus_Circle_Green Not capable of getting rid of the viruses, the size of which is considerably smaller than 0.3 microns

Ionic Purifier (Otherwise referred to as an Ionizer)

In fact, an ionic purification system cannot be called a filter by definition since it does not take the air in. What it does instead is produce electrical charges that make the contaminative particles stick together in masses that become too heavy to continue floating in the air.


prosCapable of getting rid of extremely small particles measuring 0.01 microns

prosGets rid of viruses, bacteria, smoke and toxic fumes particles, thus completely sterilizing the air


Minus_Circle_Green Purifies air but does not eliminate the contaminative particles. Since they are left in the room, there is a certain chance they might end up floating in the air once again

Minus_Circle_Green Cannot get rid of unpleasant smells and odors

Ultra Violet (UV) Light System

This specific air purification system is a perfect choice for the aim of removing various kinds of airborne pathogens from the room. Bacteria and even the tiniest viruses stand no chance since this system destroys their DNA molecular bonds by exposing them to its ultraviolet electromagnetic radiation. At the same time, this specific type of air purification has no influence on allergens or dust particles, which makes it a truly good choice only in combination with other filters.


prosEffectively destroys bacteria, germs, and viruses — potentially hazardous pathogens

prosReduces the risks of catching a disease


Minus_Circle_Green Cannot get rid of dust particles, as well as various allergens

Minus_Circle_Green Cannot purify air from gases, chemical fumes, smokes, and their odors

Carbon Filter

Owing to countless tiny pores pf activated carbon, this filter type effectively catches and retains a number of different contaminative particles. Those include the small particles that make up gases and chemical fumes, various smokes and odors. However, carbon filters cannot get rid of all types of pollutants, which is why there are usually used in combination with filter of other types.


prosHas the highest absorption power among all other filter types

prosEasily gets rid of chemical fumes, gases, different smokes, smells, and odors

prosRetains the absorbed pollutants inside preventing them from getting back into the air


Minus_Circle_Green Not capable of eliminating allergens, including dust partciles

Minus_Circle_Green Not capable of catching airborne bacteria and viruses

How Powerful Your Desired Air Purifier Should Be

The next important criterion for your choice of a perfect air purifier for your specific needs is its power indicator, which is reflected in the space coverage of the device. A super-powerful model covering more space than you need is obviously a waste of money, just as a purifier that fails to purify all the air in the room.

When taking a closer look at different models that are now available on the market, you will notice that they are designed for a range of space sizes. As a rule, you will find specific indications explaining the purifying power of the device with phrases like “Room Size” or “Average Coverage” and a figure in square feet. While a less powerful machine will do a good job in a room of up to 150 square feet, other models will offer twice or thrice as much power.

What you need to do at this stage of your search is to calculate the square footage of the room where you would like to use your future air purifier. To make it even easier, you can make use of this online square footage calculator.

Pay Special Attention to the Air Changes Per Hour (ACH) Rate

Another technical characteristic you should pay attention to is air changes per hour, or ACH rate, which is indicated by every air purifier model you can find. It shows the number of times per hour that the whole volume of air from the room goes through the purifier. For instance, if you see the ACH rate of five, it means that when used in a space it is designed for, the air purifier filters the air in the room five times in one hour.

It is highly recommended not to purchase models with an ACH rate of less than four. It is especially important if the main reason you are looking for an air purifier is to improve the quality of life when suffering from asthma or allergies.

Take Into Account the Clean Air Delivery Rate (CADR)

Apart from the ACH rate, you need to pay additional attention to the CADR rate, which stands for “clean air delivery rate”. This characteristic is essential since it describes the effectiveness of air purification that the specific device can provide in three main categories: pollen, dust, and tobacco smoke. The strategy is simple: the higher the indicators are, the better air purification results you can expect.

How Much the Ownership and Maintenance of Your Device Will Cost

When choosing an effective air purifier for either home or business, the majority of buyers take into account the price tag only. However, there is another important characteristic — cost of ownership — that considerably influences the final expenditures you will have to face. The cost of ownerships is largely contingent upon the specific air purification technology and filter type (or types), which in their turn determine the energy consumption of the air purification device.

If you are thinking about opting for an air purifier with a carbon filter or true HEPA technology, you should be perfectly aware of the real cost and frequency of filter replacement. The latter might vary from few months to few years, which substantially changes the cost of maintenance. To have a clear picture of all the costs you will deal with after you buy the desired air purifier, take some time to calculate the expected energy consumption and the maintenance expenditures within a year.

Choosing an air purifier to suit your needs turned out to be a harder task than you expected?

Compare air purifiers in the most convenient way you can find, evaluating their characteristics side by side. There is no better and quicker way to make a well thought-out choice, especially when you know what specific features you are looking for.
