GermGuardian Air Purifiers Review

Filtration

The smallest GermGuardian air purifiers are desktop units, which you don't see with many other manufacturers. These won't filter large spaces, but they still pack in the same key features that set some of GermGuardian's larger purifiers apart, including HEPA filters, UVC sanitizers and special filters to reduce odors in the air. The company lists CADR ratings for each of its units on their product pages, but they're not always in the same place, so you may have to hunt around for them. These vary widely depending on the size of the unit, but they tend to be pretty competitive with other air purifiers of the same size.

Capacity

GermGuardian air purifiers are designed for spaces up to 402 square feet. This should be large enough to accommodate most rooms in most homes, but those with larger spaces may have to consider a different manufacturer with units that can cover bigger rooms. The company's website does make it easy to filter your results based on the size of the space you plan to use the purifier in, so that can save you a lot of time when comparing your options.

As for the footprints of the units themselves, they vary quite a bit depending on the size of the air purifier, but most are compact enough that you shouldn't have too much difficulty fitting them into your space. You can view sizing information on the purifier's product page before you buy it to make sure it'll fit in your room.

Features

Your air purifier's features will depend on which model you end up going with, but you can expect to find multiple speed levels and wheels on most units. There are also models that come with timers so you can program them to run at certain times and models that have voice control so you can turn them on or off from across the room. Several GermGuardian air purifiers also include indicator lights that let you know when your filters need replacing and some also have air quality monitors that can detect when air quality in the room is deteriorating and automatically start running so you don't have to remember to turn it on.

Cost

GermGuardian air purifiers range in price from around $60 to about $400. This is pretty affordable as far as air purifiers go, so it's a good place to begin your search if you're on a budget. Most units also come with a warranty, but how long that warranty lasts depends on the unit. You can purchase replacement filters on the company's website. Prices range from around $10 to $100 depending on which filter you need. Your owner's manual has this information and you can preview it on the air purifier's product page before you make a purchase so you can better estimate the ongoing costs of the unit.
