Germ Guardian AC4200W Air Purifier Features and Specifications

Germ Guardian AC4200W features physical dimensions of 9.17 x 9.17 x 13.5 inches (~23.3 x 23.3 x 34.3 cm) and it weighs 6.55 pounds (~3 kg).

Germ Guardian AC4200W is a corded unit and it comes with 6 feet (~1.8 m) long power cord.

The unit features a 360° air intake and top exhaust.

Thanks to its dimensions and stylish design, the Germ Guardian AC4200W air purifier may easily fit in any room or office.

Germ Guardian AC4200W is a true HEPA air purifier - it is able to capture 99.97% of 0.3μm or larger particles. Also, thanks to the activated carbon air filter, Germ Guardian AC4200W also captures odors, smoke, smells, VOCs (Volatile Organic Compounds), etc. making it suitable for people having pets or issues with asthma, allergies, and similar.

Note: since indoor air tends to have much more air pollutants than outside air, having a true HEPA air purifier is recommended for all people, especially in periods of larger outdoor air pollution.

Controls are placed on top of the unit and are fairly simple:

- On/Off button turns the unit On and Off. Also, it is used to reset the filter indicator.

- Speed button sets the fan speed - there are four fan speeds including Sleep Mode and Turbo Mode,

- Timer button allows the user to set the time for 2, 4, or 8 hours.

When the unit is in Turbo Mode, Germ Guardian AC4200W features CADR ratings of 68 for smoke, 76 for dust, and 77 for pollen, making it suitable for rooms up to 105 ft² (~10 m²), ensuring four air purifications per hour.

Turbo Mode and Timer ensure fast air purification for limited operating time, allowing the user to quickly purify air after being away for some time (there is no Auto Mode).

But, in everyday use, many people just leave it to work constantly in Sleep Mode - set and forget - letting the unit constantly keep the air cleaner and safer to breathe.

Germ Guardian AC4200W uses Germ Guardian FLT4200 True HEPA Air Purifier Replacement Filter, which is basically a 2-in-1 air filter:

- activated carbon air filter stops larger airborne pollutants and captures smells, odors, and VOCs, and protects the true HEPA air part of the filter.

- true HEPA air filter captures very fine airborne particles, ensuring that the Germ Guardian AC4200W exhausts practically clean air only.

Note: Germ Guardian AC4200W doesn't feature a UV-C lamp nor the layer of Titanium Dioxide (TiO₂) nor the air ionizer, keeping the unit simple and the operation ozone free. Also, although the Germ Guardian AC4200W is a rather simple unit, when it arrives, be sure to thoroughly read the User's Guide in order to get accustomed to your new air purifier.

The air filter is NOT washable but can be cleaned using a vacuum cleaner and a gentle dusting brush. Also, the Germ Guardian AC4200W air purifier is shipped with its air filter in the bag, to prevent any pollution from reaching the air filter - prior to the very first use, be sure to remove the air filter from the bag!

Germ Guardian FLT4200 air filter should be replaced every 6-8 months, depending on the use and amount of air pollution.

Also, if required, Germ Guardian offers Germ Guardian FLT42CB4 Carbon Replacement Filter (in packages of 4) - these can be individually wrapped around the Germ Guardian FLT4200 air filter, prolonging the lifetime of the main air filter.

Germ Guardian AC4200W true HEPA air purifier comes with a 3-year limited warranty.
