Night mode senses the rooms lighting to turn off the display lights and the Plasma Ion generator, and reduces noise to whisper quiet levels⁴. AP300 models Colour Indicator and % of the cleaner air measured (based on particulates detected by the Sensor, which is translated to a % of good air quality as defined above). Personally, I don’t think the filter will last longer than 6 months. Even Instant points out that their calculation on filter life is based on running the air purifier in eco-mode for 24 hours per day. So if you’re going to run it at a medium speed 24/7 the air filter might wear out faster, after 3 or 4 months of usage.

When the light blinks orange, filter needs replacement Touch and hold for 3 seconds to reset after you've replaced filter This Instant™ Air Purifier will start delivering cleaner air in minutes and completely recycles the room’s air five times per hour³. True HEPA-13 filter captures 99.97% of dust, dander, pollen, allergens and other ultrafine impurities in the air As you can see from the table above, the number of air changes per hour drops significantly after 600 square feet. And spaces over 900 sq. ft. won’t be properly ventilated at all (required minimum for living room is 2 ACPH, see recommendations). But as for the advertised space of ~ 400 sq. ft., Instant air purifier AP300 definitely works. In rooms smaller than 400 sq. ft. this air purifier will definitely remove any allergy symptoms (especially if you consider pollen as a source of it). Maintenance Costs Small Instant Air Purifier AP100 As for the Instant AP100 air purifier, it is small and can be used for a small bedroom or bathroom, but it doesn’t have enough power to clean air in any room larger than 200 square feet.EXCEPT AS EXPRESSLY PROVIDED HEREIN AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, INSTANT BRANDS MAKES NO WARRANTIES, CONDITIONS OR REPRESENTATIONS, EXPRESS OR IMPLIED, BY STATUTE, USAGE, CUSTOM OF TRADE OR OTHERWISE WITH RESPECT TO THE APPLIANCES OR PARTS COVERED BY THIS WARRANTY, INCLUDING BUT NOT LIMITED TO, WARRANTIES, CONDITIONS, OR REPRESENTATIONS OF WORKMANSHIP, MERCHANTABILITY, MERCHANTABLE QUALITY, FITNESS FOR A PARTICULAR PURPOSE OR DURABILITY. Both Instant air purifiers offer the same 4-stage air filtration system with 3-on-1 air filter and ionizer. The only difference between their filters is its size, as the bigger the filter is, the more airborne particles it can capture in one go and it requires less time to clean air in a room.

If you’re being all out for super-quiet air purifiers, take a look at Rabbit Air cleaners. These machines are ultra-quiet, probably the quietest on the market today. PriceAdvanced filtration system: HEPA-13 filter captures 99.97% of dust, dander, pollen, smoke, allergens and other ultrafine impurities in the air; carbon layer in the filter helps reduce odors CLEAN AIR IN MINUTES: Filters up to 1,140 SQFT per hour, to exchange 228 SQFT 5 times per hour, allowing you to breathe cleaner air in minutes, based on 3rd party testing. So I’ve got 2 Instant air purifiers: one for me small bedroom (model AP100) and the other one for my living room (AP300). On a surface they look similar, but obviously the unit for smaller space is smaller in size and looks more “beefy” in diameter. The Instant AP300 is taller and looks more sleek.
