Get ready to combat hay fever with one of our favorite air purifiers for allergies — now 20% off in the Amazon Big Spring Sale

Looking for a high-performing air purifier to gear up for the upcoming hay fever season, but do not want to spend hundreds of dollars? Then do not miss this Amazon Big Spring Sale deal — one of our favorite air purifiers for allergies, the GermGuardian AC4825E, is now discounted to $79.99.

Rated as the best budget option in our guide to the best air purifiers for allergies, this humble looking appliance is equipped with a certified HEPA filter able to trap 99.97% of particles as small as 0.3 microns, a charcoal filter designed to capture larger airborne allergens, and an UV-C light for added sanitation. The GermGuardian AC4825E impressed us with its ease of use and good value for money, which is why we rated it a strong 4 out of five stars.

True, this air purifier may be too small to pull its weight in large indoor spaces, and it does not come with any smart features typical of more premium appliances, but its compact build makes it a perfect choice for those with little floor space available, and you will not need to spend hours studying the manual to get a grasp of its settings. 

The GermGuardian AC4825E is a great air purifier for those on a tight budget, and right now you can get it even cheaper — but hurry, this deal will not last long.
