4. How often should I change the filters?

Typically, filters last 12-14 months depending on daily usage time and air quality in your area. HEPA and carbon filters should be replaced annually in high-pollution areas. Your purifier also has a filter replacement indicator to alert you when it’s time.

5. Other brands claim filter life of 2 years or 5 years etc. why not CRUSADERS ?

Typically, True HEPA & CARBON along with TiO2 Photo-Catalyst filters last 3500 hours maximum and even that is depending on the air quality in your area. For example a smoker’s house the filters will get exhausted faster in comparison to a normal home. So the life of a filter is very heavily dependent on the environment it is being used in. Making false claims on filter life is a bad way to misguide a customer and lure him towards a product without giving facts on after sales support.

As a matter of fact, if you run a machine with choked filters it will likely cause you more harm and even damage the main machine motor. Hence our units come with an inbuilt filter life indication which tells you when a filter is choked and it needs a replacement.

6. Do your air purifiers remove viruses, including COVID-19?

Yes, our purifiers use UV-C light and Plasma Ion technology, which are scientifically proven to kill or neutralize viruses, bacteria, and pathogens. The HEPA H14 filter captures particles as small as 0.3 microns — including virus-carrying aerosols.

7. Are Crusaders Air Purifiers energy-efficient?

Absolutely. Our models consume between 32W to 55W, making them ideal for 24/7 use without significantly impacting your electricity bill.

8. Is it safe to use the purifier while sleeping?

Yes, our purifiers feature Sleep Mode, which runs at ultra-low noise levels and dims the lights for undisturbed rest. The timer function can also be used to automatically switch off after a set duration. It is recommended you always have the air purifier on at night as thats when your breathing is relaxed and your lungs should get the best air quality.
