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. Advanced 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 Eco mode cycles the fan on and off every 10 minutes, if air quality is detected as good for 30 minutes, allowing 50% energy reduction (Energy Star certified)

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. Living with allergies and asthma requires a home equipped with air filters and/or purifiers. We’ve been able to test out a few filter systems in our home, and with COVID a new concern, our requirements are even greater than before. This new Air Purifier from Instant Home adds some impressive new features we’re trying out. Bottom line: the Instant AP300 is proving that it’s a seriously effective room air purification tool. From its advanced filtering, to its enhanced germ killing technology, and its easy-to-live with design, the Instant AP 300 is very easy to recommend. It’s intelligent automation relieves me of having to fuss over one more thing in my life. The biggest surprise of all is how it matches the performance of a purifier costing 5X its price. Night mode senses the rooms lighting to turn off the display lights and the Plasma Ion generator, and reduces noise to whisper quiet levelsThis review is fromInstant - HEPA Air Purifier for Large Rooms Removes 99.9% of Dust, Smoke, & Pollen with Plasma Ion Technology - Pearl Advanced 3-in-1 filtration system: HEPA-13 filter captures 99.97% of dust, dander, pollen, allergens and other ultrafine impurities in the air; carbon layer in the filter helps reduce odours; antimicrobial coating prevents bacterial growth on the filter and protects it against degradation. All in all, I really love this air purifier. After the initial setup, which was a breeze, it just sits in the corner of the room and keeps the air clean without being noisy or distracting. I would recommend this for any home/room. It’s easy to use, quiet, and subtle. An antimicrobial coating prevents bacterial growth on the filter and protects it against degradation

Performance claims are calculated based on testing of a single particulate, A. Niger (mold) E. Coli (bacteria), S. Epidermidis (bacteria) or Phi-X174 (virus), under laboratory conditions following 1 hour of air purifier operation at the maximum fan speed and with plasma ion technology on. Actual results may vary, depending on usage environment (temperature, humidity, room size and shape, nature and number of particulates in air, etc.), placement of the unit, and product usage (operation duration, operation mode, etc.). Best results with continuous use.
