This Edenpure purifier review begins with the basics: what it looks like and who makes it. The Edenpure G-7 Whole Home Air Purifier looks like a small stereo speaker or karaoke machine, with a wooden cabinet and a black mesh front with control buttons and a remote. It measures 12.75 x 8.875 x 8.75 inches and weighs 16 lbs. It is made by Edenpure, a division of Suarez Corporation Industries (SCI), which is a direct marketing company based in Ohio. They make an extensive line of products for health, fitness, weight loss, and home care.

What technology?

• Ozone

The Edenpure G-7 uses four methods to eliminate indoor air pollution. It has an ozone generator, an ultraviolet light source, an ionizer, and a HEPA filter. It claims to purify the air in 3,000 square feet of living space. The ozone generator works by producing ozone, a strong oxidant, which is used to remove the smell of smoke after fire damage, as well as musty mold smells and even the smell of decaying flesh.

• UV Light

The G-7′s ultraviolet irradiation sterilizes air that is forced past its UV lamps. The UV source and filter are designed to remove the dead microorganisms that have been killed by the UV light. The ionizer in the Edenpure G-7 uses electrically charged surfaces to create electrically charged ions. The ions latch onto airborne particles, which then are drawn to a charged collector plate. The fan-based ionizer in the Edenpure G-7 is an efficient ionizer, cleaning and distributing clean air quickly. 

• HEPA filter

The Edenpure G-7 has a permanent HEPA filter with a removable, washable pre-filter. HEPA stands for "high efficiency particulate air," and is designed to remove 99.97% or more of particles that measure 0.3 micrometers. HEPA filters are effective down to particles 0.01 micrometers in size, but are ineffective for particles smaller than that. In the G-7, the HEPA filter follows the removable pre-filter, which removes the more coarse air impurities so that the HEPA filter does not clog with them. HEPA filters do not generate harmful byproducts.

Problems?

The biggest concern about products like the Edenpure G-7 is the ozone generation. While ozone does work wonders to reduce odors from musty basements, pets, and other household smells, it is also considered a health hazard when it is used long-term. The Edenpure G-7 creates 360 mg of ozone per hour, putting it in the middle range of home ozone generators, but many experts believe that is enough to be hazardous. Used in unoccupied rooms (no humans, no animals, no plants), however, the ozone generator works safely. The California Air Resources Board (CARB) identifies the Edenpure as a potentially hazardous ozone generator.

Returns?

Edenpure comes with a 60 day guarantee, and returns require original packaging. The machine carries a one year warranty. Users have had problems with customer service, however, particularly getting through to them in the first place, reporting recorded messages blaming a high volume of calls for the delays. While the Edenpure G-7 Whole Home Air Purifier may be safe for purifying rooms that are not occupied, there are enough concerns about the levels of ozone produced by the machine that any Edenpure purifier review would be remiss not to mention the potential dangers.

Why buy an air purifier?

People who are prone to allergies often have trouble with mold spores, pet dander, pollen, and dust as well as secondhand smoke. Today’s air purifiers are capable of capturing particulates to reduce the concentration of contaminants in the air, and can be quite useful for people who have allergies or asthma. An air purifier can also reduce the necessity of frequent room cleaning by getting dust and particles out of the air before they have a chance to settle on surfaces.

Air purifiers can also reduce cooking smells, pet smells, and other unwanted odors in the home.

The Hamilton Beach 04163 Air Purifier is marketed as being “99.97% effective” at capturing small particles in the air. This is only partially true. In this review, I’ll give you a clear picture of what the 04163 can do… and whether it’s worth the investment.

How it Works

A true HEPA filter is the heart of the Hamilton 04163. Wrapped around the HEPA filter are several components that make the purification process more effective.

The first of these components is the charcoal carbon prefilter. Sitting just behind the intake grill, air flows through the carbon prefilter and is scrubbed of odors and large particles (such as dust). The air then flows directly into the HEPA filter.

The HEPA filter does most of the grunt work. It extracts pollen, smoke, dust, molds, bacteria, viruses and other undesirable particles. This particular HEPA filter is 99.97% effective at the eradication of small particles. But, what’s important to note, it can only clean air that makes it into the filter.

Air that leaks from the unit before hitting the HEPA filter won’t enjoy the same level of purification.

After the HEPA filter spits out this odorless, dust free air it is met with one more purifying component; a UV germicidal light. The UV germicidal light exists to do one thing; to kill any remaining airborne microorganisms. These are the same microorganisms that lead to allergies, asthma and general sickness.

By the time air is released, the Hamilton 04163 Purifier has captured particles as small as 0.3 microns. This makes it one of the most effective purification units in its price bracket. But remember; this level of effectiveness only applies to air that flows through the unit from beginning to end.

Added Benefits

A 3-speed fan circulates air in the immediate vicinity. You can set the unit to auto, and it will adjust the fan speed depending on air quality. Meaning that the fan speeds up automatically when particles are detected and slows down when it’s clean.

The AirSmart Sensor does two things: first, it gives a clear readout of how much filter life is remaining. You’ll always know when to change the filters for maximum effectiveness. Second, it tells you how clean the air in the room currently is. The air quality scale shows a reading of poor, fair or good at all times. Therefore, you can adjust fan settings to compensate for drops in air quality.

This is not a big air purifier, making it ideal for smaller locations such as bathrooms or small garages. It is effective in rooms up to 350 square feet. Any bigger and you’re likely to see a drop in effectiveness.

Dimensions are 25x18x13 inches, making this a unit that lends itself to discretion. If you have a room where a noticeable purifier won’t do, this may be the perfect alternative.

The price point is incredibly aggressive, especially considering the UV light and HEPA filter. I’ve been hard pressed to find a similarly feature-rich unit below $300.
