GermGuardian AC4825 3-in-1 Air Purifier Review

This is a solid choice for an air purifier under $100 that will effectively clean the air of a small bedroom or living space.

PROS

The GermGuardian AC4825, 3-in-1 Air Cleaning System with True HEPA, UV-C and Odor Reduction, 22-Inch captures 99.97% of allergens with TRUE-HEPA filtration including dust mites, pet dander, plant pollens. The American Academy of Pediatric Allergy and Immunology Doctors recommends TRUE-HEPA air filtration to reduce exposure to indoor asthma triggers. This air purifier is CADR 100+ rated for up to 155 square feet and has a good reputation for reducing odors and mold spores especially in smaller rooms when the doors and windows are closed. This unit is equipped with indicator lights that let you know when to replace the filter or UV-C bulb which is convenient for those who might not keep track of how long it has been since the last time they were replaced. The GermGuardian AC4825 is inexpensive to buy and inexpensive to run – it uses very little electricity even if run continuously.


CONS

When first used there is a “new plastic smell” which can be very strong but diminishes over time. When first purchased you might want to run it in a separate room until the smell dissipates. The unit will run louder when the filter needs changing which can be very distracting. The blue UV-C light may be too bright for some to sleep at night but it can be switched off. If you are looking to purify the air of a large space, then this model will not work for you. Instead you should check out large room air purifiers, since this one can only effectively reduce the pollution in a space that is less than 150 square feet, which is about the size of your average bedroom.


MY RECOMMENDATION

I recommend this product to anyone with allergies to pollens, dust, or who is asthmatic. It’s a solid choice for an air purifier, is easy to clean and maintain, and it is an affordable air purifier that runs very well. I also recommend it for parents who are concerned about the air quality that their children are breathing, who want to free their space of allergens and mold. It also works well for pet lovers who are sensitive to pets’ hair and dander, and will alleviate your allergy symptoms.

What are the replacement parts for the GermGuardian AC4825?

The GermGuardian AC4825 has minimal replacement parts which are easily removed and replaced. The carbon activated pre-filter should be cleaned once per month or more often if needed. After a few months, cleaning it won’t remove any pollutants, so the GermGuardian FLT4825 replacement filter has to be switched out once every three months or less depending on your air quality, especially if you have pets, are a smoker, or your air is polluted with allergens. The GermGuardian LB4000 5-watt light bulb should be replaced every 10-12 months depending on how often you use your air purifier.


How easy is it to clean the GermGuardian AC4825?

The GermGuardian AC4825 air purifier should be cleaned at least once every month. Use a clean, dry, soft cloth to wipe the external surface. The TRUE-HEPA filter is a combination filter. The Pre-Filter and Charcoal Filter are combined into one layer that attaches to the HEPA Filter. The outer Pre-Filter / Charcoal Filter attached to the HEPA Filter should be cleaned every month. It can be vacuumed with the brush attachment of your vacuum cleaner. More frequent cleaning may be required depending usage and environment. The Pre-Filter (thinner one) can be rinsed off about every two weeks (carefully, it can tear easily) if used heavily in dusty, pet hair environment. Rinsing the pre-filter out with cool water regularly will help prolong the life of the HEPA filter that works with it. The HEPA filter should not be washed but replaced when it changes from white to nearly black. This will vary by use. If it is still white it does not need replacing.
