Germguardian AC4020 VS. Avari Air Purifier

The integrated ESF filter helps to capture and eliminate airborne-pollutants as small as 0.1 microns including cigarette-odor.

It’s designed to purify air in rooms of up-to 160Square Feet. Additionally, it features air-inlets at the top-section and air-outlets at the base.

Polarized germs, bacteria and viruses can be easily trapped and destroyed by the ESF filter.

Non-polarized dust-mites and fine-dust can be collected by the induction of static electricity as the air-particles pass through the ESF-filter.

The Patented ESF-filter captures pet-dander and other airborne-particles smaller than 0.1-microns at an efficiency of 99.97%.

The ESF-filter can trap and destroy pollen and other airborne-pollutants at a rate of 99.97%.

Its ESF-filter is composed of a uniquely dimpled high polymer synthetic resin film that helps to trap and eliminate smoke during the air-purification process.

Non-polarized mold-spores are also collected by the induction of static electricity as the particles pass through the ESF filter.

Uses a Patented ESF filter to capture and eliminate 99.97% of allergens and other airborne-particles smaller than 0.1 microns.

This unit is whisper-quiet whereby it generates only 36-decibels at the maximum-speed-setting and 9-decibles at the lowest-fan-speed making it quiet as an average library.

It features easy-to-replace filters than can be accessed by simply removing the top-cover. In fact, you don't need any tools to replace the filters.

This device operates in auto-mode by default. So, it will run in turbo-mode when starting to cleanup-air and afterwards go automatically into quiet-mode when air is cleaner.

It will automatically go into quiet/sleep-mode after cleaning air for a couple of hours. In fact, it will operate silently with the LED-lights on/off.

Uses only 5.2 watts at the highest fan-speed which makes it very energy-efficient.

It’s Energy-Star Certified for low power-consumption of just 5.2-watts at the highest speed setting.

It features an auto turbo-mode and quiet-mode coupled with a power-button for switching it on and off.

It uses only 5.2-watts on a turbo-mode which is less than 1.5 cents per day hence making it very economical and energy-efficient.

It is affordable yet it covers a reasonable surface-area and removes move air-pollutants like other advanced air-purifier models.

It will work perfectly for homes with asthmatic-people because it features a Patented ESF filter that captures 99.97% airborne-pollutants and allergens.

It features an easy to maintain filter that can be replaced within 12-to-18 months depending on the air-pollution levels in your area.

Its ESF-filter helps to eliminate airborne-pollutants without producing ozone and other carbon-components.

It features a sleek, compact and tower design with a LED-light that can be turned-off when you sleep or left on for subtle night light.

Has a dimension of: 12.5 x 11 x 14.5 inches coupled with a sleek, compact white-body with LED-light and power-button.

7.05-pounds and this makes it very lightweight and easy to carry from one room to another.
