The new ENERGY STAR qualified, Honeywell True HEPA Allergen Remover effectively captures up to 99.97% of airborne allergens, 0.3 microns and larger, that pass through the filters. This air purifier is highly effective at capturing airborne particles such as dust, smoke, pollen, pet dander and mold spores in extra large rooms (5x air changes per hour in a 465 sq. ft.). An odor reducing pre-filter and True HEPA filter are paired to capture odors, VOCs, allergens and germs. The Honeywell HPA304 True HEPA Whole Room Air Purifier With Allergen Remover offers easy tap controls and an automatic shut off timer.

A+ Genuine Pre-Filter

This air purifier works with the Honeywell A and A+ Pre-Filter. The Pre-Filter is the first level of filtration and helps capture large particles such as dust, lint, fibers and pet fur and helps to reduce VOCs & odors from cooking, smoke, bathrooms and pets. This filter should be replaced every 3 months. The filter check/reset light will remind you when it’s time to change your filter. Initial filter included. To ensure stated product performance, use only genuine and certified Honeywell replacement filters.

R Certified True HEPA Filter

The Certified Honeywell True HEPA R Replacement Filter helps capture up to 99.97% of microscopic allergens, 0.3 microns & larger from any air passing through the filter. For optimal cleaning performance, replace your HEPA filter every 12 months. The filter check/reset light on the HPA304 Air Purifier will remind you when it’s time to change your filter. Initial filter included.

Any air purifier that is AHAM (Association of Home Appliance Manufacturers) Verifide means that it has been independently tested to ensure its efficiency in reducing smoke, dust and pollen in the suggested room size. The AHAM assigns a CADR (Clean Air Delivery Rate) Rating that measures the volume of filtered air delivered by an air cleaner. The Honeywell HPA304 True HEPA Whole Room Air Purifier received the following CADR Rating:

  • 5 Air changes per hour in a 465 sq. ft. room
  • Tobacco Smoke: 300
  • Dust: 320
  • Pollen: 300

Whether you have allergies, asthma or simply want access to fresher, cleaner air in your home, the Honeywell Store has an air purifier for you. Here are a few of the benefits a portable air purifier can offer:


Releases Cleaner, Fresher Air Back into Your Room

  • Honeywell Air Purifiers pull in contaminated and dirty air, forcing it through a robust filtration system. This process removes pollutants while capturing odors and volatile organic compounds (VOCs). The result is cleaner and altogether fresher air being circulated back into the setting. Honeywell Air Purifiers feature an AHAM Verifide rating that reveals how efficient they are in reducing smoke, dust and pollen (results are based on model and room size).


Captures up to 99.97% of Microscopic Allergens1

  • Certified HEPA Filters in Honeywell Air Purifiers capture up to 99.97% of both larger airborne allergens and other microscopic particles as small as 0.3 microns from the air that passes through the filters. Honeywell Air Purifiers offer a highly effective solution for capturing airborne particles such as dust, smoke, pollen, pet dander and mold spores.


Helps Reduce Certain Airborne Virus, Bacteria & Mold Spores2

  • A selection of Honeywell HEPA and Air Genius Air Purifiers have been tested to effectively help reduce certain airborne viruses, bacteria & mold spores from the air that passes through the filters.


The Doctor’s Choice: Honeywell Air Purifiers are the #1 Brand Recommended by Allergists3

  • Physicians can often recommend air purifiers as part of a treatment plan designed for allergy/asthma sufferers.

1From the air that passes through the filter, 0.3 microns and larger.

2Based on 3rd party independent CADR testing for the smoke CADR value when operated at the highest level. Air circulation depends on many factors, such as room size and configuration. There is no guarantee that all of the air in a room will pass through the filter.

3Based on March 2018 Cascade Survey Research results reporting 48 out of 70 (69%) surveyed Allergists that recommend a brand of portable air purifiers to their patients, recommend “Honeywell” air purifiers as their first choice.

Operates fairly quietly. Have not had to operate yet during bad conditions like smoke in outside air, but assume it will perform very well.

The smoke from Oregon fires showed red on our air quality indicator and then purple as we drove our motorhome in search of cleaner air. Because of my asthma, we had the Honeywell between us as we drove with our generator powering it. It was truly a life saver.
