Blueair PRO XL VS. Blue Pure 211

It features patented HEPAsilent-technology with particle filtration and electrostatic charge to eliminate 99.97% of airborne-pollutants.

This device is designed for use in large-rooms with sizes between 1000sq.ft and 1200sq.ft. Likewise, it’s AHAM-rated at 1184sq.ft which makes it ideal for use in larger-rooms.

Uses an optional SmokeStop carbon activated filter to get rid of gaseous pollutants like cigarette-odor.

It’s designed to be used in larger-rooms between 1000sq.ft and 1200sq.ft. It also uses a SurroundAir-system which offers 5 air-changes per hour in different room-sizes.

The particle-filter uses HEPASilent-technology to capture 99.97% of airborne-pollutants like germs down to 0.1-microns.

It uses HEPASilent-Technology with particle-filtration and electrostatic-charge to capture 99.97% of airborne-pollutants like dust-mites.

This device uses a particle-filter with HEPASilent-technology to destroy 99.97% of airborne-pollutants including pet-dander.

Its HEPASilent-particle-filter helps to trap and eliminate 99.97% of airborne-pollutants including pollen.

An Optional SmokeStop-filter creates an extra-level of activated carbon filtration in-order to get rid of smoke.

This device uses HEPASilent-technology to eliminate 99.97% of air airborne-pollutants including mold.

Its HEPASilent particle-filter combines an electrostatic-charge and mechanical-filtration to eliminate 99.97% of allergens and other airborne-pollutants.

Pro works so silently on its lowest setting because its equipped with German Engineered fans that ensure an ultra-quiet yet powerful operation.

The filters are very easy to replace and the process doesn’t require using any special tools.

The integrated Air Intelligence Module (AIM) helps to automatically test particle and gas levels in your indoor air and adjust fan-speed to maintain a clean-air environment.

It can be set at the lowest fan-speed so as to ensure whisper-quiet operation with dimmed lights.

Uses 33-watts on lowest speed-setting and 256-watts on highest speed-setting.

Its Energy-star rated for low-energy consumption most especially when running on lowest fan-speed.

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

Features a filter change light that will alert you when it’s time to change the filter.

This device is a bit economical since it uses only 33-watts on the lowest-fan-speed.

The patented HEPASilent particle-filter helps to remove 99.97% of airborne-pollutants that cause asthma and other airborne-allergies.

It’s recommended to replace the filters every 6-months or depending on the usage and air-quality of your environment.

This unit is certified by the California Air Resources Board for not producing ozone. It even has an internal-ionizer that ensures zero-ozone emission.

Has a Professional, sleek and Swedish design coupled with a tower-shaped body with a display-panel and manual-controls located at the top.

Features dimensions of 44"H x 20"W x 10"D. It also features a tower-shaped, galvanized steel housing with a powder coated finish coupled with a white body-color with dark-grey grills.

It features a weight of 32-kgs (71-lbs) which makes it a bit heavy to carry and move from room-to-room.
