  • HEPA Filters

  • Activated Carbon Filters

  • Antibacterial and Germicidal Filters

  • pre - Filters


  • Heat Filtration


HEPA (High Efficiency Particulate Air) Filters efficiently clean allergens such as pollen, animal skin and dander, mold spores, and dust. HEPA filters remove at least 99.9% of all the particles as small as 0.3 microns.

Air purifier using HEPA filters have to be periodically changed.

HEPA certified filters work well for all common particle allergens, but remember not all HEPA filters are created equal.

The larger the HEPA filter, the more particulate it will be able to remove. The size, material, and construction of the actual filter plays a vital role in the air purifier's performance.

Air Purifiers which produce Ozone as their main product/by-product are strictly not recommended.

Filtration technology which is ozone free and uses HEPA and Activated Carbon Filters is more effective and widely used option. HEPA filter based Air Purifiers are the only type of Air Purifiers which meet specific health and safety standards.

Room Size

When choosing an air purifier, the size of the room is an important factor. Bigger spaces will need larger air purifiers and vice versa. Buy an air purifier that designed to operate in a space that is 20-40% larger than room for optimal performance.

CADR Ratings

Clean Air Delivery Rate or CADR denotes how efficiently and quickly an air purifier works. It tells you how many cubic feet of air can be filtered in one minute for different categories such as pollen, dust and smoke. Larger rooms will need higher CADR ratings to ensure effectiveness.

Air Change Rate

The ACH (or the air change per hour rate) tells you exactly how many times the air purifier filters the entire room’s air in one hour. If an air purifier that has 5 ACH, it means that the air in the room will be filtered every twelve minutes.

Indoor Air Quality Indicator 

A light indicator changes color in response to the indoor air quality, so that you can adjust the fan speed accordingly. A higher-end Air Purifier is usually equipped with an Auto Mode function, which would adjust the speed setting in response to the indoor air quality automatically.

Some newer models are also available in the market with numerical PM 2.5 display. These help you measure and see exactly how bad the air is.

Filter Replacement & Customer Service 

A filter needs to be changed usually after every 12-18 months, so the filters should be readily available. One should always look out for pre and post sale demonstration / installation service option provided by the manufacturer.


As Air Purifier is a costly product and a longer period warranty coverage is beneficial so that you do not face any issues and can be assured that your product runs smoothly for years.

Factors affecting Individual Situation

Construction Area - A pre filter is a must for people residing in construction areas as there is a lot of dust. HEPA ‑filter helps in removing pollution arising from vehicular emission.

Factory area/area with issue of gases with smell - Activated Carbon ‑filter is a must as it can absorb those harmful gases on it’s surface. Be sure to check the filter before purchasing.

How to get the most out of your Air Purifier?

Clean or replace filters regularly : As a general rule, you should replace them (or clean those that can be vacuumed) every six to 12 months for pleated filters and every three months for carbon filters.

Place it wisely :  If you have just one unit, place it in the room where you spend the most time. For most people, that’s the bedroom. Make sure to place the air purifier in a spot where nothing can obstruct airflow—away from curtains, for instance. For more, read our article on how to choose the best air purifier for your home.

Keep your purifier running 24/7 :  Keep doors and windows closed while it’s in use. We suggest running the unit on the high setting when you’re not in the room and turning it down to low when you’re nearby. Or buy an air purifier certified for a larger area so that you can run it on a low speed and still have it work effectively.

Other Ways to Improve Indoor Air Quality

Vacuum regularly. No air purifiers can remove the larger allergens—dust mites and pet hair, for example—that settle on furniture and carpets unless it gets disturbed and redistributed into the air. Use a vacuum with a HEPA-certified filtration once or twice a week to clean floors and furniture.

Use an exhaust fan in the kitchen. Do the same in bathrooms and laundry rooms.

Stop smoking indoors. That also goes for burning candles and wood fires.

Ventilate. Open your windows on nice days to let in clean, dry outdoor air. If pollen or related allergies keep you from opening windows, run your air conditioner or forced-air cooling system with a clean air filter

Reduce the use of chemicals. Limit chemical-heavy cleaning products, and don’t store paint, glues, or insecticides near your living quarters.
