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 The AP200 Instant™ Air Purifier is ideal for medium sized spaces like kitchens, home offices and bedrooms. It can remove 99.97% of ultrafine airborne impurities and 99.9% of virus, bacteria and mould particles from treated air ¹ .

The LIGHT level of the display can be manually selected (4 levels) but it reverts to AUTOMATIC during the next DAY or NIGHT mode occurrence. Holding down the preferred LIGHT mode for 3 seconds keeps it in that setting. As for the sound levels, Instant air purifiers aren’t leaders in this department. The small unit is quiet on low speed, but somewhat noisy at a high speed, despite it not being powerful. There are so many amazing benefits with the Instant Air Purifier. Aside from how great it is at purifying the air, here are a few of the pros with this system: The sizes could be larger– The largest size filters up to 388 square feet. If you have a larger space that you are wanting cleaner air in, then you would need multiple units.A small amount of energy is used– While the air purifier is relatively energy efficient and the eco mode is a huge benefit, air purifiers do still use energy as opposed to not using one at all. However, they also provide cleaner air and contribute to a healthy home. So the pros and cons should be weighed out! My Honest Review: Why I Love It Cleaner air in minutes: Starts delivering cleaner air in minutes and completely recycles the room’s air five times per hour; Works hard, saves energy; Eco mode cycles the fan on and off every 10 minutes, if air quality is detected as good for 30 minutes Eco mode cycles the fan on and off every 10 minutes, if air quality is detected as good for 30 minutes

I got my Instant air purifiers unassembled, but putting inside the air filter was very easy. I had to remove the base, unwrap the filter, put it inside and close the bottom panel. All steps are described in user manual, so it’s a no-brainer. Review
