Honeywell HPA300 HEPA Air Purifier

Honeywell HPA300 HEPA Air Purifier

Honeywell HPA300 air purifier is a powerful device that can help clear the air of allergens, including those from wildfires. It’s designed for large spaces, like those in larger rooms and homes.

The HPA300 is a very powerful air purifier. It uses two pre-filters and a HEPA filter to trap pollutants down to 0.3 microns, making it one of the best for trapping smoke particles. The HPA300’s display also gives you easy access to a lot of information about the purifier’s settings, like its current speed in ACH (air changes per hour), the relative humidity, and the amount of CO2 in the air.

The HPA300 can be programmed with a schedule so it can clear the air while you’re away from home. It also includes some basic modes, such as an “allergy” setting and a “clean air” mode that cycles through speeds 1-4. You can also choose to set it to one speed while you’re at home and another while you’re away.

However, this purifier is also large and heavy: it measures 18.9 x 14.2 x 8 inches and weighs 27 pounds. It’s too big for smaller rooms but perfect for larger spaces like apartments, offices, or even homes with kids who suffer from allergies.
