Honeywell HPA600B Professional Series Features

Honeywell HPA600B is recommended for large rooms, up to 325 square feet (~30 square meters) and is designed to filter air in such rooms up to 5x per hour, significantly decreasing amount of air pollutants, allergens, odors and VOCs (Volatile Organic Compounds).

Honeywell HPA600B doesn't feature WiFi connectivity and some users consider it as an issue, while other users like its relative simplicity regarding its use and maintenance.

Honeywell HPA600B features include:

- Air Quality Indicator: this unit comes with particle and VOC sensors which constantly monitor the air and with the air quality indicator light with three colors to indicate the air quality: blue (good air quality with low level of particles and VOCs), amber (medium air quality with moderate level of particles and VOCs), or red (low air quality with high level of particles and VOCs).

- 5 Air Purifying Levels: Level 1 (Sleep), Level 2 (Germs), Level 3 (General Cleaning), Level 4 (Allergens), and Turbo Mode. When the unit is turned on, it starts with the Level 2.

- Auto Sensing Mode allows the user to let the unit check and if required to automatically change the mode of operation. Auto Sensing Mode indicator light shows current mode: blue (good air quality with low level of particles and VOCs, air purifier operates at Level 2), amber (medium air quality with moderate level of particles and VOCs, air purifier operates at Level 3), or red (low air quality with high level of particles and VOCs, air purifier operates at Level 4).

- Timer Auto-Off Mode allows the user to set the unit to automatically turn off after 2, 4 or 8 hours.

- Dimmer allows the user to adjust the brightness of the LED lights on the control panel.

- Check Filter Indicators alert the user when it is time to change the air filters.

Honeywell HPA600B features 4-layers air purification system, based on 2 mesh pre-filters and 2 3-in-1 air filters. While 2 mesh filters are washable, 3-in-1 air filters must be replaced, on average, every year.

Recommended filter replacements are OEM 3-in-1 True HEPA Filter Kit (HRF-Z2) consisting of two individual filters, featuring HEPA air filter, antimicrobial coating which prevents the growth of microorganisms on the filters, and the third layer made using activated carbon granules which capture odors and harmful VOCs.

Note: Honeywell HPA600B is rather simple to use and maintain air purifier, but before the very first use, be sure to thoroughly read the manual.

Honeywell HPA600B has air inlets on the sides and the exhaust of the purified air on the top of the unit - such air pathway maximize the air filters' surface and minimize energy required for everyday operations. Also, top exhaust mix the air in the cleaned room, decreasing the temperature difference between air layers, making the room even more pleasant to live in.

Honeywell HPA600B Professional Series Specifications

Honeywell HPA600B is large and rather heavy unit. Its physical dimensions are (LxWxH) 16.73 x 9.45 x 24.25 inches (~42.5 x 24 x 61.6 cm) and it weighs 32 pounds (~14.5 kg). It features two handles and castor wheels for moving around, but generally, place it on the permanent floor position and move it slightly only when vacuuming around the unit - and vacuum often, since the air flow attracts the dirt that is often builds up near the unit.

Honeywell HPA600B features AHAM verifided CADR ratings of 210 for smoke, 184 for dust, 205 for pollen. Personally, its CADR ratings could be better, but don't forget that this is true HEPA air purifier that captures 99.97% of 0.1 microns or larger particles, while most other true HEPA air purifiers capture 99.97% of 0.3 microns or larger particles.

This 0.1 vs 0.3 microns difference doesn't sound much, but the smaller the particle, the deeper it enters the lungs when being inhaled.

Honeywell HPA600B consumes 44 watts when set on the high power setting.

Also, it comes with 5-year limited warranty.

Honeywell HPA300 is cheaper unit with ~50% larger CADR (Clean Air Delivery Rate) ratings, but although it is true HEPA air purifier, Honeywell HPA600B has better air purification, it is more energy efficient model, with several features not present on HPA300 model, like Auto Sense Mode, Air Quality Indicator and similar.

Personally, if you do need good HEPA air purifier without advanced features, go for Honeywell HPA300 model - set it to operate at low speed and forget it until it requires some maintenance.

But, if you do need an air purifier with exceptional level of air purification and automatic operation, consider Honeywell HPA600B model.
