What Type Of Filter Should I Choose An Air Purifier With?

When buying an air purifier, many people tend to buy an air purifier with more modern air filters. But many of the built-in air filters can become redundant during use. You should buy an air purifier that has the filters you need most. 

For example, if you are allergic to pet dander or pollen, you should buy a machine with a HEPA filter or an ion filter. If you are allergic to odors or suffer from rhinitis, you can choose an air purifier with a filter with a UV lamp.

Usually, air purifiers on the market have a lot of filters, and below is some information about the popular ones.

Firstly, the prefilter is the most common one. Prefilters are usually made of materials such as metal, plastic, or glass. This filter is often used to filter any dirt particles such as hair, pet hair, cotton fibers, etc. Also, its cost is quite cheap, but it cannot filter fine dust, bacteria, and toxic air like other types of filters.

Secondly, an equally popular filter is the HEPA filter. This filter can filter dust from 0.3 microns and a variety of bacteria and molds. However, this filter still cannot remove viruses and many types of toxic air.

Thirdly, a filter overcomes the disadvantages of the two above filters, which is a negative ion technology filter. This filter generates negative ions to absorb all bacteria. However, it also has the downside that it can produce ozone that is harmful to you.

There are still some quite popular filters on the market, such as activated carbon filters, UV filters, etc. Therefore, you can only choose the best air purifiers based on your purposes and needs.

What criteria should be kept in mind to be able to choose the best air purifiers?

First of all, the filter is an important part that contributes to keeping the air in your room clean. But not all filters can be used forever, so you need to consider the life of the filter. You should pay attention to cleaning and seeing the filter regularly. Typically, low-priced air purifiers have a shorter filter life than high-priced air purifiers.

Furthermore, like other types of household electrical appliances, the larger the device's capacity is, the larger the airflow is. You must base on the area of ​​the room to choose the most suitable air purifier.

Last but not least, when buying household appliances, they will inevitably be damaged during transportation or even during installation. It would help if you chose brands with a clear return and warranty policy that best suits you. Such brands are sure to produce high-quality products rather than disreputable brands.

In addition to purifying the air, what other functions does the air purifier have that are worth a try?

The best air purifiers are often equipped with a lot of extra functions, most notably two: controlling humidity and diffusing essential oils.

In particular, each region has different weather characteristics; users also need to choose a machine with features suitable for the characteristics of where they live. In places with cold and dry weather, priority should be given to purifiers with ion generating functions to dehumidify. Areas with a hot, dry climate, with a lot of rain and low humidity, need an air purifier with a humidifier function to prevent dry skin.

Moreover, some of the other best air purifiers also work as essential oils diffusers. These types of machines not only purify the air in your home but also allow your room to be filled with your favorite scents. However, note that only put in the machine the essential oils that have the most gentle and pleasant scent because not all essential oils are good for you.
