Air Purifiers for Allergies: How They Work and Which Ones Are the Best

With increasing air pollution and the rising numbers of respiratory issues in a large group of people, it has become more important than ever to have air purifiers at one’s home and workplace. This is mainly important for those individuals who have allergies or are more prone to them.

Although normal air purifiers might help in reducing respiratory irritations in people who have allergies, there also exist special air purifiers made for the convenience of people who are prone to allergies. These are the ones containing HEPA filters. Such filters use activated carbon and other purifying elements which help in filtering out allergens from the air. As most people spend the majority of their time indoors, the use of such an air purifier becomes necessary and is a great addition to one’s home or workplace. But before opting for such purifiers, one should know how they function to remove allergens from the surroundings. 

Air Filters


How They Work:

HEPA filters are also referred to as High-Efficiency Particulate Air filters. Just like their name, they are built to efficiently remove the allergens in the air and clean and purify it. It is a mechanical-based filter and has a pretty fine mesh with very tiny openings through which the air is forced to pass. Due to its nature, the mesh can trap a lot of pollutants and allergens like pollen, dander from pet animals, mites, dust and even tobacco smoke. All these are very common allergens and the air purifier’s ability to trap them can be of great benefit to people with these common allergies.

The Best Air Purifiers For Allergies:

Besides knowing how such purifiers function and work, it is very important to know which are some of the best and highest-rated options for HEPA filter air purifiers that a person can choose from. Below are two of the best purifiers for allergies suited for different needs and room sizes:

Molekule Air Mini+

If one does not have a huge budget but still wants to get an air purifier, then this model by Molekule can be a great option. Air Mini+, as the name suggests, is a smaller unit that can easily be carried from one place to another. This makes it portable and can be a great option for those who would want to carry their purifying machines from one place to another like from a particular room in the house to another. It weighs around 5 kilograms and hence is not that difficult for anyone to handle or carry in general.

But one should not be fooled by its portability and size alone. Although small, it can clean the surrounding up to 250 square feet. This limit is fit for medical use as certified by the FDA. The machine also comes with a strap which can be used to easily carry it from one place to another without having to awkwardly hold it. The durability of the purifier’s filter is for up to 6 months after which it has to be changed. For this, the company’s website also provides a subscription under which the timely delivery of new filters needed to replace the older ones would be done so that one does not simply forget to change them. So, overall it is a great option for people who either live alone or have only a couple more roommates and those who want to make the transition into using air purifiers an easier one. But it may not be the best for people who expect their machine to clear a larger area or those who expect a bigger-sized machine.
