Germ Guardian AC4825

This fantastic Air Purifier is long and narrow, coming in at 9 x 5.5 x 21 inches, and weighing in at 7lbs. The Germ Guardian is a sleek and safe machine. It can even be kept out of view whilst it works, as it takes up such little space.

You’ll find that the Germ Guardian can filter the air up to 4 times in an hour of rooms up to 167 sq ft, meaning you get the best quality air quickly and continually throughout the day. Want to personalize your Germ Guardian’s work? It has 3 speed settings so you can choose the perfect output.

Germs, dust, pollen, pet dander, mold spores…the Germ Guardian AC4825 takes care of them all with its true HEPA filter. It traps all these allergens and more, even ones as small as .3 microns in size. Not only will the Germ Guardian trap these harmful particles, it kills them instantly too, with the specially designed UVC light and titanium dioxide within it.

That’s not all though, because this air purifier helps to reduce stale, lingering odors. With its activated charcoal filter, you’ll find a reduction in unwanted and unpleasant odors from pets, smoke, cooking fumes and more.

You won’t even know the Germ Guardian’s running either, with its quiet operation that means it can be used any time. On its lowest setting, it even emits white noise, aiding a quiet, restful sleep and working on your air for the best results. And, the UVC light can be turned on and off as desired, so it won’t interrupt your rest.

With dimensions of 15 x 8.2 x 23.6 inches, and weighing in at 15.4lbs, you’ll find the Winnix a larger air purifier that works hard to rid your home of unwanted air particles. With the extra size though, comes extra power, and this air purifier is certainly hiding a few extra tricks up its sleeves.

You’ll find the Winnix perfect for medium and larger rooms, including family rooms, bedrooms and kitchens. In fact, it works to purify the air in any room up to 360 sq ft, working to replace the air numerous times per hour.

When it comes to working smarter, the Winnix has it all. In fact, with its Smart Sensors, you can leave this air purifier to its own devices, as it gauges the air quality of your room and auto adjusts its own 4 fan speeds to the perfect choice to filter the air correctly.

This air purifier is quiet enough to be left working throughout the day, no matter what your plans. Plus, with sleep mode, you can let the Winnix work throughout the night. It won’t disturb your sleeping patterns and will leave you waking up and feeling more refreshed than ever before.

When it comes to filtering out the bad stuff, the Winnix works hard. Its true HEPA filter ensures that particles as small as .3 microns are trapped and eliminated from your home. That’s not all though, because with its activated carbon filter, you’ll find pesky odors removed from the air, leaving a fresh and pleasant smell in its place.

When it comes down to it, it’s clear that the Winnix 5500-2 has a few extra functions to play with, on top of the wide range that both air purifier’s share. For that reason, the Winnix wins this round.

With that being said, the Winnix, a larger model, is built for larger rooms, so, if you’re looking to cleanse less room space, choosing the Germ Guardian will still give you a fantastic clean, for a cheaper price, just without the added extras.
