Best Eco Air Filters by Anca Novacovici

The Best You Can Get

  • NQ Industries Clarifier Medical Plus

    Anca says: The NQ Clarifier Medical Plus air purifier offers an advanced purification system to treat many types of air pollutants. It uses four levels of filtration, including a True HEPA filter, Activated Carbon filter, pre-filter, and post-filter, as well as a comprehensive purification zone that destroys bacteria, viruses, fungi, and molds. Contaminated air is continuously re-circulated with a large 350 cfm fan and through four inlet grills, and up to 99.97% of particles 0.3 microns or larger are removed. In addition, the NQ Clarifier Medical Plus air purifier features specially-sealed internal components which prevent internal leakage, and the patented interior reflective chamber amplifies the intensity of the four UV lamps by up to 66 percent.

    • Capacity: 1,500 square feet
    • Air Purification Method: Pre-filter, HEPA filter, activated carbon filter, post-filter, and 4 UV lamps
  • Atmosphere

    Anca says: The Atmosphere 101076 (white) and 102858 (blue) room air cleaners provide very high performance removal of air pollution. The filtration process goes through three stages, each removing a different kind and size of particle from the air. Stage 1 uses a pre-filter to remove large particles, which helps extend the life of the main particle filter. Stage 2 uses a HEPA filter offering a very effective means of trapping sub-micron particles. The benefit of this filter technology is that it provides an extremely long life filter with high particulate removal, low maintenance and no harmful byproducts. The filter technology also allows a high airflow, which reduces electrical consumption and noise. Stage 3 is the carbon filter, will reduces gas-phase odor molecules, without producing any harmful byproducts, through the use of a special combination blend of chemically impregnated activated coconut shell carbons. This carbon both adsorbs and reacts with the molecules, trapping them as well as converting some of the molecules into harmless salts, gases and water vapor. The filter also contains two catalysts that help destroy formaldehyde.

    The unit qualifies as an Energy Star rated appliance and feature a remote control unit with five operating speeds, a programmable timer, an integrated particle sensor, and an electronic monitoring system that alerts you when the filters need replacing or cleaning. The system is also backed by a two-year limited warranty.

    • Available in white (101076) or blue (102858)
    • Capacity: Can clean a 390 sq. ft. space in approximately 30 minutes
    • Three pre-installed filters: a cleanable pre-filter, a replaceable carbon (odor) filter, and a replaceable HEPA (particulate) filter
  • Airgle 750

    Anca says: The Airgle 750 received the highest clean air delivery rate (CADR) of all the room air cleaners tested by the Association of Home Appliance Manufacturers (AHAM). This rating correlates to Tobacco Smoke > 450 CADR, Dust > 400 CADR, and Pollen > 450 CADR. The Airgle 750 has many convenient features, and even has an aromatherapy capability. The unit is easy portable with heavy-duty, easy-glide casters that let you move it from room to room. There is a three-year manufacturer’s warranty on the product.

    The Airgle 750 has lots of gadgets, including a programmable LCD Control Panel that lets you adjust time, speed setting, auto/manual mode, and other controls. It also has a timer that can be set so the unit will shut off after one to eight hours of operation, a light sensor for silent mode that turns the unit to silent mode when the room is dark, and a sensor that checks pollution levels in the environment and automatically adjusts fan speed for the best performance. To top it off, the unit monitors the usage and operating conditions to remind you when the filters need attention.

    • Capacity: 698 sq. ft.
    • 12-stage filtration technology - 4 permanent pre filters, 4 HEPA filters, 2 activated carbon filters, and 2 high air flow filters – air filtration media with antimicrobial agent
  • Blue Air ECO10

    Anca says: The Blue Air ECO10 is the latest model in the line of Blue Air room air cleaners, made in Sweden. It builds upon the already impressive technology and performance of other Blue Air models. The highlight of the ECO10 is its energy efficiency. It is by far the most energy efficient room air cleaner on the market, using about 95% less energy than other air cleaners in its class, and performing about 10 times better than the minimum Energy Star performance criteria. The ECO10 uses a mere ten watts of power! Just think of the money you will save by not using all that energy! It is able to achieve these amazing results by using an Ultra Efficient EC Fan Motor.

    It gets even better… the unit has a lifetime warranty, should only need a filter change once a year, and utilizes 3 HEPA-Silent Filters (pre-filters prolong the life of other filters) that can trap particles down to .1 micron in size. It received a CADR rating of Smoke – 190, Dust – 195, and Pollen – 200. Blue Air has several measures in place to prevent polluting the environment through the manufacturing and use of their products. One such example is using nontoxic polypropylene filter media that produces only carbon dioxide and water as it decomposes, making it 100% recyclable when used and non-toxic to landfills or the air. These units are extremely quiet, to the point that you might even wonder if it is on. Through precision engineering, the ECO10 allows air to flow easily through it, instead of requiring loud and powerful fans and motors to push air through the unit.

    • Capacity: About 300 sq. ft.
    • Combines patented HEPASilent™ filter technology with a superior EC fan motor
    • Other features include two built-in speeds, four effective pre-filters and a main filter unit that can be vacuumed to prolong service life
  • IQ Air: HealthPro Plus

    Anca says: The IQ Air products are recognized as some of the best room air cleaners in the world. IQ Air makes several models of room air cleaners, each with its own special purpose. Their products range from removing typical household allergens all the way to Clean Room technology for medical spaces. IQ Air company claims that the HealthPro Plus room air cleaner is probably the best all around allergen, particle and toxic gas purifier in the world. That is a pretty bold claim but considering that this is the very same air purifier model that was chosen by the Hong Kong Government Hospitals for use in the SARS wards, it may be well justified. If that wasn’t enough, take a look at this list of awards that the HealthPro Plus has won: Allergy Buyer’s Club: Category Winner, Wired Magazine Test: Best Air Purifier, Consumer Guide – Best Buy, Reviewboard Magazine: Product of the Year, Consumer Digest – Best Buy, Test Magazine: Category Winner, and Newsweek Odor Tested.

    The key to the success of the HealthPro Plus model is that it contains HyperHEPA filter technology, which can remove particles down to 0.01 microns with close to 99% efficiency. HyperHEPA is the technology that is used in today’s multi-million dollar Clean Rooms and hospitals. In addition to the HyperHEPA filters, the HealthPro Plus also contains a Revolutionary V5-Cell gas filter for removing a wide range of gaseous contaminants and odors. A cool feature of the IQ Air models is that they have a filter sensor built in that will tell you how much longer each individual filter will last before it needs to be changed, down to the hour. There are 6 different fan speeds on the HealthPro Plus, so you can customize its performance to meet your specific needs. An automatic timer allows you to program the unit to work even when you aren’t around. IQ Air goes to great lengths to ensure that each of their products is functioning properly. When you purchase an IQ Air product, you receive a two-page Certificate of Performance that verifies they have tested your individual unit and it passed the test.

This revolutionary filter media is one of the least harmful plastics, producing only carbon dioxide and water as it decomposes. Because polypropylene is waterproof, the filters naturally resist contamination from bacteria, viruses and mold, without chemical additives or washes. BlueAir even uses a special powder coat finish that produces no chemical offgassing. Used filters are 100% recyclable, and release no toxins into landfills or the air.
