GermGuardian AC4825 air purifier is modern looking device which resembles small tower, 22 inches (~56 cm) tall. It can blend in most rooms and offices and silently do its job – clean the air. It operates using mains power – 110/120V, 60 Hz. If you are not from US, be sure to order model which can use local electricity.
One of the most important aspects of air purifiers is air filtration – GermGuardian AC4825 filtration is done in three stages:
– first stage: a mechanical pre-filter is combined with a charcoal filter to capture larger particles like dust and lint, and to remove common household odors, including pet odors, cooking odors, smoke and similar. This stage protects rest of the filtration system from larger particles and chemicals and increase filter life.
– second stage is based on a ‘True HEPA filter’ which captures 99.97% of pollutants 0.3 microns in size or larger. These include particles like mold spores, dust mites, plant pollen, pet dander, larger smoke particles etc. Some manufacturers claim that their filters are, for example, 98% HEPA or similar. That is marketing trick – if it is HEPA, then that filter stops 99.97% of 0.3 micrometers or larger particles.
– third and final filtration stage of protection is based on UV-C light, which kills (actually, it damages the DNA of viruses and bacteria so they will die eventually, sometimes not right away) airborne viruses and bacteria, while activating titanium dioxide (TiO2) to help decompose odor molecules caused by smoking, cooking, pets etc. The light-bulb used in AC4825 emit ultraviolet light at 253.7 nm, so GermGuardian AC4825 doesn’t emit ozone in the room (it would require ultraviolet light of 200 nm or shorter to produce ozone).To simplify use, GermGuardian AC4825 is equipped with indicator lights for UV-C bulb and filter. When onboard controller detect that it is time to replace the bulb or filter, it will notify the user.
When turned on for the firs time, it is possible for indicator lights to start blinking. When that happens, simply reset the system by holding the UV button for 3-5 seconds or until the reminder lights stop flashing. After that, air purifier is set and ready to operate.
GermGuardian AC4825 is ‘CADR rated 100+’ (CADR stands for ‘Clean Air Delivery Rate’ and is measured in cubic feet per minute (CFM)).
Being rated CADR 100+, GermGuardian AC4825 is suitable for smaller rooms and areas, up to 150 square feet. If you regularly vacuum your room with HEPA grade vacuum cleaner and amount of air particles is not high, air purifiers like this can be used even in larger rooms. If you do have larger room, you will require at least two of these purifiers or consider buying larger model.
