What is the Honeywell HPA600B Air Purifier?

The Honeywell HPA600B is a premium True HEPA air purifier from Honeywell’s Professional Series, designed for large rooms up to 325 square feet with smart features and advanced filtration. It was part of Honeywell’s top-tier air purifier lineup, offering superior air cleaning capabilities with the convenience of modern smart technology.

What made the HPA600B special was its combination of powerful True HEPA filtration (capturing 99.97% of particles as small as 0.3 microns) with innovative features like the InSight Display that shows real-time air quality and filter status. The unit also included Bluetooth connectivity for remote control via smartphone app, automatic operation modes, and a comprehensive 3-stage filtration system.

At its core, the HPA600B uses a 3-stage filtration system: a washable pre-filter for larger particles, a True HEPA filter for microscopic pollutants, and a separate activated carbon filter for odors and VOCs. This comprehensive approach made it particularly effective for allergy sufferers, pet owners, and anyone concerned about indoor air quality.

The unit was Energy Star certified and featured four cleaning levels, including a Turbo Clean mode for rapid air purification. With dimensions of 18.5 x 16.5 x 26.5 inches and weighing 21.6 pounds, it was substantial but designed to blend into home environments with its professional black finish.

Performance and Smart Features Analysis

The HPA600B’s performance stood out in several key areas that justified its premium price point. After analyzing user feedback and technical specifications, I found that its air cleaning capabilities were particularly impressive for large spaces.

The InSight Display was one of the HPA600B’s most innovative features. This illuminated display provided real-time feedback on air quality, filter status, and current cleaning level, allowing users to see exactly what the purifier was doing at any given moment. The display could be dimmed for bedroom use, addressing a common complaint about bright LED lights on air purifiers.

Bluetooth connectivity was another standout feature that set the HPA600B apart from many competitors. Through the Honeywell app, users could control the purifier remotely, monitor air quality, and receive filter replacement notifications. This smart functionality made it convenient for users who wanted to manage their air quality without being physically present.

The Auto Mode feature was particularly impressive for hands-off operation. The air quality sensor would automatically adjust the cleaning level based on detected pollutants, ensuring optimal performance while conserving energy when air quality was good. Users reported that this mode worked well for maintaining consistent air quality without constant manual adjustments.

In terms of air cleaning power, the HPA600B featured four cleaning levels: Germ, General Clean, Allergen, and Turbo Clean. The Turbo Clean mode was especially effective for rapid air purification, achieving multiple air changes per hour in the recommended room size of 325 square feet.

3-Stage Filtration System Breakdown

The HPA600B’s 3-stage filtration system was the foundation of its air cleaning effectiveness. Each stage played a crucial role in removing different types of airborne pollutants.

The first stage featured a washable pre-filter that captured larger particles like dust, pet hair, and lint. This pre-filter could be cleaned and reused, helping to extend the life of the more expensive HEPA and carbon filters. Users appreciated this cost-saving feature, as pre-filters could typically be vacuumed or washed every 2-3 months.

The second stage contained the True HEPA filter, which was the workhorse of the system. This filter captured 99.97% of microscopic particles as small as 0.3 microns, including pollen, mold spores, dust mites, bacteria, and other fine particulates. The HEPA filter in the HPA600B was designed to last approximately 12 months with regular use.

The third stage utilized an activated carbon filter for odors and volatile organic compounds (VOCs). This filter was particularly effective against smoke, cooking odors, pet smells, and chemical fumes. Unlike some combined filters, the HPA600B kept the carbon filter separate, allowing for more targeted odor removal.

Filter Replacement Considerations

One important consideration for the discontinued HPA600B is filter availability. While the HRF-Z2 replacement filters are still available, potential buyers should consider long-term availability. The filters cost approximately $108 for a pack of two and should be replaced annually for optimal performance.

For those considering a used HPA600B, it’s important to factor in filter replacement costs. The total annual maintenance cost would be around $54 per year for filters, which is reasonable for a premium air purifier but something to budget for when evaluating the overall value.

Noise Levels and Energy Efficiency

When it comes to noise levels, the HPA600B performed reasonably well for a large-room air purifier. On the lowest setting, most users found it quiet enough for bedroom use, though some light sleepers found the lowest setting still noticeable in very quiet environments.

On higher settings, particularly the Turbo Clean mode, the HPA600B became significantly louder, as expected from a unit moving large volumes of air. Users reported noise levels ranging from approximately 30 decibels on the lowest setting to 65 decibels on Turbo Clean, which is typical for air purifiers in this class.

The dimmer feature for the control panel was a thoughtful touch that addressed concerns about LED brightness in bedrooms. Users could adjust the display brightness or turn it off completely while the purifier continued operating, making it more suitable for overnight use.

Setting	Approximate Noise Level	Suitable For	Air Changes/Hour
Lowest Setting	30-35 dB	Bedrooms, quiet environments	2-3 ACH
Medium Settings	40-50 dB	Daytime use, living areas	4-5 ACH
Turbo Clean	60-65 dB	Rapid cleaning, temporary use	8+ ACH

Energy efficiency was another strong point for the HPA600B. As an Energy Star certified device, it consumed relatively little power for its air cleaning capabilities. Users reported minimal impact on their electricity bills, even with continuous operation. The Auto Mode feature helped optimize energy usage by adjusting the fan speed based on actual air quality needs.

Typical energy consumption ranged from 30 watts on the lowest setting to 90 watts on Turbo Clean, which translated to approximately $3-8 per month in electricity costs depending on usage patterns and local electricity rates.

Current Alternatives to HPA600B
