ifD Micro-Filter
^ Honeywell AirGenius 5 HFD320 filters/ technologies/ lifespan
Like all Honeywell AirGeniuses, the patented QuietClean ifD technology that eliminate up to 99.9% of microscopic allergens as small as 0.3 microns. The washable/ odor reducing pre-filter will capture large particles like dust and harmful gases, while the permanent honeycomb washable ifD filter will handle other smaller micron size allergens, germs and bacteria. Oscillate can also be activated via a touch of a button. The filtration works reasonable well although it's incomparable against traditional HEPA and carbon filter media. Another thing is the 2 permanent filters requires regular maintenance/ cleaning (quarterly or when necessarily) to prevent dust and other particles from clogging up the filter thus reduce its efficiency.

Vastly efficient when pit against large and tiny pollutants, allergens, irritants, viruses and bacteria. Powered by immense airflow input/ output and wide purifying coverage, the permanent filtration is terrific in eliminating dust, hair, pet hair, pet dander, dust mites, pollen, mold and mildew.  On smokes and odors, the permanent filtration is weak in handling chemicals, odors, cooking smell, fire, VOCs, tobacco smokes, cigarette, vapor, radon and ammonia.

Keep it down

QuietClean technology generates very little noise particularly in the first 2 speed (SLEEP and GERM mode). For night time use, you can run the air purifieri in SLEEP mode where the air purifier runs whisper quiet while setting on Maximum performance, the MAX Cleaning Power (fifth speed) noise is audible but perfectly bearable. Honeywell AirGenius 5 HFD320 is Energy Star certified so power consumption is on the low side which uses less than a light bulb upon lower speed selected.

With the washable foam pre-filter and permanent ifD QuietClean technology, Honeywell AirGenius 5 HFD320 won't cost you any additional dime upon purchase. Even if you do opt for the odor reducing pre-filter upgrade (fully recommended), at most +- 64 would be the annual filter replacement cost.

Final thoughts on Honeywell AirGenius 5 HFD320

If you need a top end tower air purifier to kick start your journey to a cleaner air, Honeywell AirGenius 5 HFD320 takes the cake (apart from AirGenius 4). Its exterior is eye-catching, multiple timers setting, maintenance free yet powerful ifD filter and the smart controls has its charm of its own.
