Buying Guide 

Considering buying an air purifier? Know that there are more than a hundred options available in the market from renowned brands. It is indeed quite important to choose one that will cater to your requirement for clean air in the long-term.

TYPES OF AIR-PURIFIER

a. HEPA Purifiers

These are the most commonly chosen purifiers for homes. It utilizes an age-old tried and tested method of eliminating microscopic particles from the air. These are high-efficiency purifiers that can filter up to 99.97% of airborne germs. As it functions, the filters become much more effective and do not produce any harmful by-product. You can also combine filtration technology with other forms of purification for better efficiency. However, the cost of replacing filters is relatively higher. 

b. Activated Carbon Air-Purifiers

Air-purifiers that use activated carbon filters usually have a high absorbent ability which is quite effective for detecting pollutants, odour, smoke and microbes in the air. If the user has multiple chemical sensitivity, this is the ideal option for them.

c. Filterless Air-Purifiers

As the name suggests, these types of purifiers don’t use any filtration system. Instead, they utilize a separate mechanism to fulfil the purpose. Despite the absence of a filter, these are quite advanced and low-maintenance devices. 

d. UV Technology Air-Purifier

This particular type uses antibacterial and germicidal UV filters to destroy harmful bacteria and germs. They sterilize the air completely and are preferable for hospitals, kitchens, labs and daycare centres. 

Pre-Filters

These are foam or non-woven polyester that are perfect for eliminating relatively bigger particles such as pet hair. If you want to increase the efficiency and longevity of the purifier. At times, the technology is also combined with activated carbon filtration to remove odour and smoke from the air. 

Heat Filtration

The passing air over an inner 400 degrees C ceramic plate helps to kill the organic microscopic particles like bacteria, viruses, dust mites as well as mould. However, it is a slow process as it works by convection to keep on circulating the air. It also does not work against the non-organic particles such as smoke and chemical vapours.  

AIR CHANGE RATE 

When you decide to buy an air purifier, it is important to check the air change rate i.e., the number of times a purifier cleans the entire room air within an hour. Of course, the number depends on the size of the room and the filter. 

ROOM SIZE

The size of the room is directly proportional to the size of the filter (or purifier) that you require. But it is not always possible to come across the perfect product by only determining size. Therefore, to be on the safe side, get an air purifier that has been manufactured to operate adequately in a space that is 20-40% of the size of your room. 

OTHER REQUIREMENTS

  • No one wants their electricity bills to soar up at the end of the month for a newly-installed essential device. That is why we suggest you get an energy-star rated product that goes easy on power consumption.
  • If you don’t have budget constraints, go for a Wi-Fi air-purifier that can be controlled directly from the phone. 
  • Air-purifiers with air quality indicators are quite convenient because they give you real-time updates regarding the quality of the air that you’re breathing. 
  • For mobility, air-purifiers with caster wheels, handles are necessary. 
  • Filter change indicators are also a must because if they aren’t changed on time, your product may get damaged permanently.
