At the end of the day, there is bound to be one air purifier that would assist in solving your long-term germ troubles.

What is antimicrobial?

For centuries, antimicrobial act as an agent that inhibit the growth of microorganisms on the applied surfaces.

Best paired alongside HEPA filter, what we want from the air purifier is to have genuine antimicrobial protection that works whether it is coated on a filter or as a standalone filter.
HEPA filter All germs, bacteria, and viruses are at microscopic particles size that can only be captured by a HEPA filter. A critical component in our measurement as the air purifier simply would not work without it. With the antimicrobial potentially help lengthen HEPA filter lifespan, what we want from the HEPA filter is to work well alongside antimicrobial and have the capability in trapping even the smallest household bacteria and viruses.
Room size/ Coverage In order for the air purifier to support and capture a broad range of airborne germs and viruses, everyone would prefer the widest purifying coverage that can cover any room size. What we would take into the consideration is the machine overall size, intended target users and of course pricing factor into consideration when evaluating the airflow applicable area.

Winix HR950/ Winix HR1000 is always the first one in our mind as it is well-priced, well-equipped and is well-protected against bacteria and viruses. Any types of germs would definitely not able to bypass the bundled True HEPA filter coated with antimicrobial and PlasmaWave that create Hydroxyls to neutralize bacteria, odors, gases, and chemicals. The wide purifying coverage is also ideal for large room size including living hall, master bedroom or dining area. Features wise Winix HR950 comes with all the standard goodies including air quality sensor with display indicator, Auto mode, and timer. For added Wi-Fi support via Winix Smart app,  go for the slightly higher spec version Winix HR1000 air purifier.

Nitpicking on its negative, other than the loud fan noise and slightly high annual filter replacement cost, Winix HR950 is pretty much a flawless antimicrobial air purifier. Other similar Winix air purifiers you could also consider is the pet-focused Winix 9500, power-oriented Winix U300 or the next item in the list.
  • 5-stage filtration with PlasmaWave™ Technology.
  • Effective True HEPA filter coated with Anti-microbial protection.

  • In sleep mode, the indicator light does not dim down enough to prevent a slight glare disturbance.

Winix U450 might well be a discontinued model at the point of this writing, it doesn't discount the fact that it is handsomely equipped with a 5-stage filtration including the all-important CleanCel Antimicrobial coat. At a wide 450 sq. ft. capturing range, the 99.97% efficiency True HEPA filter will swiftly capture all household germs, bacteria, and viruses. All captured microorganisms inside HEPA filter will then be locked away by the antimicrobial from reproducing. Adding a permanent pre-filter, Carbon filter and Winix trademark PlasmaWave in the bag, you can't go wrong with this air purifier.

As mentioned earlier, Winix U450 is well-equipped with premium features like remote control and VOC sensor. The consequences of all that is obviously the higher price tag and so is the annual filter replacement cost. Furthermore, Winix U450 is a dated model so you probably would be better off with the new Winix HR950 or HR1000.
  • Minimalist design that is supported by the handy digital screen and remote control.
  • Comprehensive airflow purifying coverage that is great for large size room.
  • Impressive stats on all three dust, pollen, smoke CADR.

  • 5 years warranty with the optional extension.
  • Considerably expensive with many cheaper alternatives such as Winix P450.
  • Bundled cassette filter replacement is certainly not the cheapest in the market.

A hidden gem, little do people know that Rabbit Air BioGS 2.0 filter is actually pre-coated with an antimicrobial that inhibits any microorganism from reproducing on the filter. With the filter shielded from microorganism growth, bacteria and viruses that flows inside the air purifier would be permanently removed by the HEPA filter. Adding the supportive negative ion generator, powerful airflow distribution and large room size radius regardless of which version you go for, you have yourself an absolute winner.

Again very little fault you could associate with Rabbit Air BioGS 2.0 other than the expensive price tag. Even the annual filter replacement cost is dirt cheap. For a slimmer and more cost-effective air purifier, consider the next item in the list.

What we like about GermGuardian AC5250PT other than the attractive pricing is the comprehensive 5-stage filtration which includes key components such as HEPA filter and of course antimicrobial Pet Pure treatment. The HEPA filter would remove all airborne allergens including bacteria, germs, and viruses while the Pet Pure treatment inhibits microorganisms from reproducing. Adding the optional UV-C light, slim tower profile plus many practical features add-on, its hard to say no to this machine.

What we don't like about GermGuardian AC5250PT is the small purifying coverage and limited airflow distribution. Not great for large room size but totally acceptable given its size and price. If you want a tower air purifier with slightly higher antimicrobial airflow performance coverage, consider Fellowes AeraMax 200.
  • Affordable price for a HEPA tower purifier which cost less than half of other competitors is offering.
  • Complete 4-stage filtration with UV-light and 5 fanspeed.
  • Effective True HEPA with Pet Pure that inhibit the growth of mold, mildew and odor-causing bacteria.
  • Proven UV-C light that would assist in eliminating airborne germs and bacteria.
  • Comes with practical features such as timer, filter replacement indicator and digital display.
  • UV function can be deactivated via a button.
  • 5 years manufacturer warranty.
  • Limited purifying coverage together with average airflow delivery rate.
  • Annual filter replacement cost (with Pet Pure filter C) around the size of a brand new unit.
  • Lacks air quality sensors and Auto mode.
  • Uses combine Charcoal pre-filter rather than dedicated carbon filter.
  • Troublesome filter reset alert that requires small object like paperclip to click and reset the button.

Fellowes AeraMax 200 is the equivalent fo AeraMax 190 except it comes in white housing. The naming convention might be confusing but the rest of the specification will not be. First off, it has the mandatory AeraSafe antimicrobial treatment on HEPA filter, above average purifying coverage for a tower air purifier and effective True-HEPA filter that works as advertised against household germs, bacteria, and viruses. Adding PlasmaTrue Technology and convenience AeraSmart Sensor with air quality display and auto mode, Fellowes AeraMax 100 is no doubt a solid, well-rounded bacteria air purifier.

One tiny issue with Fellowes is that the brand is not as common as other big name models which could reflect on your buying decision. If you can bypass that, this air cleaner would definitely be worthy of a shot.
  • Modern contemporary exterior with front blue indicator on each active function.
  • Well-priced for a 4-stage filtration with abundant of features including 4 speed, Aera+ mode and Auto mode.
  • Excellent partnership between True HEPA filter and carbon filter.

You could also opt for the bigger BreatheSmart Fit50 with even wider purifying coverage or the widest coverage Alen BreatheSmart.
