Smoke, dust, pollen, pet dander and other allergens can become a problem for your overall health. A good quality air purifier helps to curb the effects of these harmful particles in the air inside your home. 

Selecting the most appropriate air purifier for your home can be a difficult task as there are some important factors which have to considered before purchasing one. Moreover, the different varieties and designs make it a little bit more tricky to make a decision.

The different types of purifiers

There are a few points which could be kept in mind while looking for the top air purifier for your home situation. For instance, what are you using it for? You might only need to get rid of odor, in which case you could opt for the Therapure air purifier. If you are looking for something which takes care of a large room, you should look at the Honeywell True Hepa air purifier which is the best large room air purifier.

These are some of the different types of purifiers to choose from:

Aside from the specific purpose you are looking for, looking at these additional features can help you to make the right decision:

  • Ionizing cleaning method
    These air purifiers use charged particles to attract other particles such as dust and pollen. The purifiers come with metal plates which attract the contaminants once they pass through the electric field. The contaminants are attracted to the plates due to the opposite charge. Some particles are even attracted to each other to charge difference which makes them heavier and eventually leads to the contaminants being settled out of the air.

  • Types of Filters
    Filters are used to clean the air which passes through them. The design and functions of the filters makes them clean the air from contaminants. Usually filters are made from cotton, fiberglass or foam. The density of the filters also plays a key role in controlling the way the air is filtered. Smaller the gap means smaller contaminants can be trapped.

    HEPA Filter

    A top rated air purifier usually uses true High Efficiency Particulate Air filters (HEPA). These able to remove particles which are under 0.3 micrometers or bigger. These filters allow only a certain amount of air to flow through them.

    Having a true HEPA filter and/or carbon filter plays a key role of filtering out odors. Some air purifiers may not be equipped with one therefore directly affecting the capabilities of the machine to give the desired performance.

  • Use of Adsorbents
    These filters use an adsorbent material to trap contaminants. The most popular adsorbent material is activated charcoal. The surface of this material makes it perfect to trap differently sized contaminants and filter the air clean.

  • Ozone Generators
    These air purifiers use electric charges or UV light to turn the passing oxygen into ozone. The ozone molecules in turn clean the air. However, the use of such purifiers is not recommended due to the health risks which are associated with ozone.

  • Clean Air Delivery Rate (CADR)
    This factor tells us how capable the air purifier is in removing harmful and toxic substances from the air. The CADR rating of the purifier is usually provided on the seal. It is required to filter the air from substances like dust, pollen and the impurities which are given off with tobacco smoke.

  • Safety of Use
    This is an extremely important factor which needs to be considered when purchasing an air purifier. Some of the air purifiers may produce ozone or other chemicals which are extremely harmful for the human respiratory system.

  • Other Features
    The design of the air purifier is also important when judging it on the basis of being a user friendly product. The overall design of the product including the LEDs, knobs, fans etc may play a key role in determining the usability of the air purifier. Features such as ionizer, carbon filter and pre filter also count.
