Holmes Small Room HEPA Air Purifier VS. Blueair Pro Air Purifier

Uses patented HEPAsilent-technology with particle filtration and electrostatic charge to capture 99.97% of airborne pollutants.

It’s built for use in large rooms with sizes between 700sq.ft and 800sq.ft. In fact, it’s AHAM-rated at 780sq.ft hence making it ideal for use in large-rooms.

This unit uses an optional SmokeStop carbon activated filter to get rid of gaseous pollutants including; cigarette-odor.

It should be used within medium-to-large rooms between 700sq.ft and 800sq.ft. It also uses a SurroundAir-system that takes in polluted-air from one side and releases clean-air on the other sides.

It uses a particle-filter coupled with HEPASilent-technology to capture 99.97% of airborne-pollutants including germs down to 0.1-microns.

Uses HEPASilent-Technology with particle-filtration and electrostatic-charge to captures 99.97% of airborne-pollutants including dust-mites.

It uses a particle-filter with HEPASilent-technology to capture and destroy 99.97% of airborne-pollutants including pet-dander.

Uses a HEPASilent-particle-filter to eliminate 99.97% of airborne-pollutants including pollen.

It uses an Optional, SmokeStop-filter to create an extra-level of activated carbon filtration so as to get rid of smoke within your house.

This device uses a particle-filter coupled with HEPASilent-technology to eliminate 99.97% of air airborne-pollutants including mold.

The HEPASilent particle-filter combines an electrostatic charge and mechanical filtration to effectively remove 99.97% of airborne-allergens and pollutants.

It’s equipped with German Engineered fans that ensure an ultra-quiet yet powerful operation. In fact, its noise-level lies between 32-to-55 dBs which makes it very quiet even at the highest-speed-setting.

Its filters are very easy to replace without needing any special tools to get the job done.

There an optional Air-Intelligence-Module (AIM) that allows you to set the device to auto-mode. This module continuously tests the indoor air-quality and automatically adjusts the speed-setting.

This device can be set at the lowest fan-speed in-order to ensure whisper-quiet operation with dimmed lights.

It uses 22-watts on lowest speed-setting and 170-watts on highest speed-setting.

This unit is Energy-star rated for low energy consumption especially when running on lowest fan-speeds.

It has a simple control-panel-display at the top featuring manual-controls for fan-speed, Led-indicators, Power-button on sides and an auto-mode activated by an optional Air-Intelligence-Module (AIM).

It’s equipped with a filter change indicator light that will alert you when it’s time to change the filters.

It’s very economical because it uses only 22-watts on the lowest-fan-speed and 170-watts on the highest-fan-speed.

It uses a patented HEPASilent particle-filter to destroy 99.97% of airborne-pollutants that cause asthma and other allergies.

It is recommended to replace the filter every 6-months or depending on use and the air-quality of your environment.

This device is certified by the California Air Resources Board for being ozone-free. It also features an internal-ionizer that ensures zero ozone emission.

Has a sleek, Swedish style and a tower-shaped body with a display-panel and manual-controls located at the top. It also features a white body-color with dark-grey grills
