This unit is more refined, logical, and favorable among homeowners. With its 21 inches height and 16 inches width, this air purifier is ideal to use in living spaces of up to 338 square feet.

When you look for affordability, GermGuardian AC5900WCA comes with a few tricks to help you save the cost of running it without having to compromise the quality of operation. The majority of the unit is plastic and is designed to look stylish.

It is the first of its kind to feature a bottom to top airflow system. To facilitate this, the device uses a huge air intake vent at the front and a smaller air outlet on the top of the unit. This design is common in more expensive units that common users wouldn’t afford. But with GermGuardian AC5900WCA, you can enjoy this feature at a very lower cost. Moreover, this device also has a common control panel with up to 5 functionality buttons.

GermGuardian AC5900WCA comes in a variety of colors including white and black. It is also quite lightweight, making it highly portable.

GermGuardian AC5900WCA Filters

This device is fitted with a 3-in-1 air cleaning system which boasts the 3 popular filter types that guarantee to absolutely purify your home.

Pre-filter: This is a normal pre-filter that features an activated carbon filter to eliminate the large airborne particles of irritants and remove all the bad smells that come from cooking, smoke, and pets.

True HEPA filter: GermGuardian AC5900WCA uses True HEPA Filter that allows it to capture 99.97% of tiny allergens, mold spores, and dust as small as 0.3 microns in diameter.

UV-C Light: This stage of air filtration uses a UV bulb to kill any airborne bacteria, mold spores, and viruses.

To boost the performance rating, GermGuardian AC5900WCA uses a new True HEPA filter, which is quite bigger than an average filter.

GermGuardian AC5900WCA Coverage

GermGuardian AC5900WCA is exactly the unit users have been waiting for. The company did well in swapping smart features for power, and as such, the device boasts a large coverage than other products by the manufacturer. The device can handle a room size of up to 338 square feet.

The ACH of the air purifier remains 4X, and with that high changes per hour rating, it can purifier the air in your living space every 15 minutes.

The CADR of the device is 220 Dust/ 218 Smoke/ 215 pollen (cfm). This CADR ranting is way better than other devices in the market. However, you should know that CADR rating is not a measure of the performance of the unit, but how fast the air purifier can clean a particular room. And with a 338 square feet room, this unit can overcome any hurdles with no hassle.

GermGuardian AC5900WCA Sound

This device comes with only 3 fan speeds, which means it operates with an average noise of an air purifier. But that should be expected with the bigger size of the unit, which requires a big fan, which in turn produces a higher level of noise.

Even the low fan setting on this device can produce a noise level of up to 40 decibels, which is quite higher than a standard air purifier. When you switch the highest fan setting, the noise level can reach up to 60 decibels. This is the kind of noise you will encounter in public coffee shops or an air conditioner at 100 feet.

GermGuardian AC5900WCA Power Consumption

Air purifiers must stay connected in the power to be efficient. However, one of the things you need to look for in an air cleaner is energy consumption. GermGuardian 5900W comes with a built-in 5 watts UV-C bulb and too much power, that subsequently result in the unit to run at 60 watts. This may not be kind to your energy bill.



GermGuardian AC5900WCA air purifier is a great unit to have at home and all the great features and attributes, you will not get a better deal than this. It has decent performance and can clean medium to a large room. Although it is a little bit nosy, I think that is something you can get used to, it is not that distracting and you can sleep quite well with the unit functioning.
