The filter is the most important part of the air purifier. It affects the purifier’s performance and usability.
Below, we present 5 different types of filters. Each of them has different parameters and is best suited for certain tasks.

  1. Cloth Filter – its surfaces are made of fabric to capture larger impurities, such as animal hair, pollen or dust. This filter is designed for mechanical removal of impurities. Sometimes, it is supplemented with a substance to remove free radicals.
  2. Activated Carbon Filter – it is the most absorptive filter currently available on the market. It has small pores and large absorptive surface. Its significant advantage is absorbing odours, both those which can bother us at home, like cigarette smoke or household chemicals, as well as formaldehyde or chemical vapours in industrial plants. Unfortunately, it does not remove allergens and microorganisms.
  3. Electrostatic-Ion filter – it is based on a simple attraction-repulsion principle. Due to an electric charge, it attracts particles with opposite charges. Ions in the purifier are negative and easily attract positive ions in the form of dust and allergens in the air. Undoubtedly, one of its biggest advantages is attracting very small particles. The device operates very quietly, because it does not contain any fans or engines. However, it does have disadvantages – it removes impurities only from the air, not from the room. Therefore, it requires frequent cleaning to ensure proper functioning. Also, it does not neutralize odours.
  4. Water Filter – it draws the air using a fan and transfers it to a water tank. It is user-friendly and cheap, as it only requires changing the water and thorough cleaning of the filter. However, it is not the optimal solution, as it increases humidity. If not well cleaned, it can cause mould, fungus and unpleasant odours.
  5. HEPA Filter – i.e. Highly Efficient Particulate Air filter – it is designed to remove most of the impurities present in the air. This applies above all to pollen, mould, bacteria, mite embryos and animal hair. Given its specificity, it is recommended by doctors and allergologists. When combined with a carbon filter, it can provide an excellent solution for comprehensive air purification!

How to make the best choice?

Once you know various types of filters, you should consider the following issues:
What kind of impurities would you like to remove from the air (pollen, mould, dust and mites, bacteria, viruses, cigarette smoke, odours, other vapours present in the air…)? Which device can best meet your expectations?
Once those questions are answered, selecting the right device should be easy. Should it be a complex filter system (several filters in one device, cleaning the air in a number of stages) or a simple unit.

Where to place the filter?

You should remember that even the biggest air purifier has a limited range and is not able to exchange air in the case of large surfaces. Therefore, it is worth considering whether one powerful unit can meet your expectations or is it better to invest in two or three smaller devices.
It is recommended to locate the purifier in the most frequently used room.

Pay attention to the operation of the air purifier. Is it loud? It this noise level appropriate? Will it become bothersome? Will the air flow cause inconvenience?

Important!
When investing in an air purifier, you should remember how important it is to take proper care of the device, especially cleaning the filter. Some models can be cleaned by the user. However, some should be maintained by a specialist. After a certain period of operation, the filter has to be replaced, because some impurities permanently adhere to the filter and cannot be entirely removed.
