GermGuardian AC4300 Air Purifier Features and Specifications

GermGuardian AC4300 Air Purifier is tower-shaped air purifier with dimensions of 8.88 x 6.38 x 22 inches (~22.6 x 16.2 x 55.9 cm) and weight of 9.45 pounds (~4.3 kg). During operation, its maximum power consumption is 55 watts (~0.5 Amps @120 volts).

GermGuardian AC4300 Air Purifier doesn't feature WiFi connectivity and can't be controlled via smartphone - most of the user consider this as its advantage, not disadvantage.

Air inlet is at the back of the unit, with the air exhaust on the sides.

Note: GermGuardina AC4300 is simple to use and maintain air purifier, but it is highly recommended to read the manual thoroughly before the very first use.

Multilayered true-HEPA air filtration is achieved by:

- Pre-filter and carbon layer filter out larger particles and remove pet and common household odors. Pre-filter and carbon layer can be replaced more often, protecting the main HEPA air filter and improving the air quality in general.

- true HEPA air filter captures 99.97% of 0.3 microns or larger particles including pet dander, dust mites, pollen and many other potential allergens.

- UV-C lamp in combination with titanium-dioxide sanitize the air and decompose remaining harmful chemicals. Since some users can be worried about the ozone production, UV-C lamp can be turned off - during testing it has been shown that ozone production is far lower than allowed. Nonetheless, it is nice to have this option.

GermGuardian AC4300 can use two types of air filters: GermGuardian FLT4825 Filter-B (yellow frame) and GermGuardian FLT4850PT Filter-B Pet (purple frame).

Both GermGuardian FLT4825 Filter-B (yellow frame) and GermGuardian FLT4850PT Filter-B Pet (purple frame) consists of pre-filter and activated carbon layer, but FLT4850PT Filter-B Pet also features so-called 'PetPure Filter Treatment', which is basically an anti-microbial agent added in order to inhibit the growth of mold, mildew, odor-causing bacteria and other germs on the surface of the filter.

Personally, GermGuardian FLT4850PT Filter-B Pet (purple frame) costs slightly more than GermGuardian FLT4825 Filter-B (yellow frame), but regardless if you have pets or not, price difference is justified - for short, when replacing the air filter, go for genuine GermGuardian FLT4850PT Filter-B Pet (purple frame) air filter.

Air filters are not washable - they should be replaced periodically, depending on the use and the amount of air pollutants present. On average, pre-filter and carbon filter (also known as the 'combination filter') should be replaced every 6 months. HEPA filter lasts longer, especially if the combination filter is changed more often - again, this is highly dependable on the local conditions!

GermGuardian AC4300 Air Purifier is controlled via simple console on top of the unit.

GermGuardian AC4300 Air Purifier console features On/Off button which also doubles as speed selector, UV-C lamp On/Off button, signal LEDs for speed, HEPA filter and UV-C lamp.

GermGuardian AC4300 Air Purifier features three speeds, with first being the slowest, but also ultra quiet and is often used during night.

Note: many users set the air purifier at speed '1' and forget about it until the filters need to be replaced. This way, unit/fan/filters are not stressed out and at the same time offer continuous air purification where required.

GermGuardian AC4300 Air Purifier features CADR ratings of 107 for dust, 116 for pollen and 99 for smoke, with the recommendation for the room up to 153 sq. feet (~14 m2) in size.

 GermGuardian AC4300 Air Purifier comes with 3-year limited warranty.
