Honeywell HPA300 weight
17 lb (7.7 kg)

One of the smallest and most compact pet air purifier in its class, Honeywell air purifier HPA300 well-shaped framework is smaller than most high-coverage air cleaner at 20.8 x 22.4 x 10.8 in and 17 lb (7.7 kg) weight. Great for most household while not so great to bring around for traveling. Usability wise is very typical of Honeywell air purifier setup with top control and indicator. It might lack air quality sensor, auto mode and remote control, Honeywell HPA300 air purifier is still well-equipped with high purifying coverage certified by AHAM, 4 fanspeed including turbo mode, electronic filter replacement reminders, light dimmer option, 2, 4, 8 hours timer, ENERGY STAR certified and 5 years warranty.

Honeywell air purifier HPA300 has an unbelievable wide 465 sq. ft. purifying coverage given its price and size. The 4 fanspeed (Germ, General Clean, Allergen and Turbo) is more than enough to support the air purifier continuous airflow purification although Auto mode is the sorely missed feature. In most situation, Honeywell HPA300 is ideal for studio apartment, living hall, kitchen and large-sized bedroom.

^ Honeywell HPA300 filters/ technologies/ lifespan
Honeywell air purifier HPA300 utilize a familiar filtration setup that you could find in other Honeywell models. First off the dual function carbon pre-filter is great at capturing large particles mainly dust while it can also capture smoke and odor particles. The subsequent True-HEPA filter will handle small and tricky airborne particles that manage to bypass the pre-filter including notorious asthma triggering pollen/ spores. No ionizer or optional addon filter is included in the machine.

Honeywell air purifier HPA300 3-stage filtration and purifying applicable area is fantastic when stand up against allergens, irritants, viruses and bacteria. It is tremendously efficient on large airborne pollutants notably dust, hair. Nevertheless against small pollutants, the4 speed airflow input/ output + is superb at taking down mold, spores, mildew, pollen, germs, dust mites and pet dander.  On odors, fumes and smokes, Honeywell air purifier HPA300 filtration is poor in addressing chemicals, odors, cooking smell, fire, VOCs, tobacco smokes, cigarette, vapor, radon and ammonia.

Keep it down

Other than the Turbo speed mode, Honeywell air purifier HPA300 is considerably silent given its airflow performance and purifying coverage. The starting Germ and General Clean speed mode is suitable for night use while Allergen mode is tad louder but ignorable. Turbo mode is expected to be loud as with most air purifier in this category. Power consumption is average compare with other Honeywell air purifiers despite the extra airflow performance. This would also depends on the fanspeed and frequently of operation.

^ Replacement filters/ estimated cost
Unquestionably Honeywell air purifier HPA300 is the best in terms of value VS pricing. Its affordable and way cheaper than most air purifiers that offers similar airflow performance. Filter replacement cost is slightly high as it utilize 3 HEPA filter pack at one go (see table specification to learn more). Nevertheless we would still not recommend going for after-market filters as it could potentially break-down the air purifier.

Slightly lower end version that has a weaker airflow delivery rate and coverage but returns with a cheaper price tag.
