Latest German engineered motor is quieter and uses up to 90% less energy saving you $142 per year on average in electricity costs.see how > Up to 1,700 sq ft (can clean multiple rooms up to 1700 sq ft. Place in room where you will spend most of your time, typically a bedroom or living area.) 220V/50 and 120V/60Hz with supplied power converter. Fine Particulates, Dust, Pollen, Mold, Pet Dander, Allergies, Asthma, Bacteria, and Light Odors. We searched the world to build the ultimate air purifiers. In Germany we found the largest factory of high performance motors, just like a Tesla engine.

So, you get high performance and reliability with low energy usage. HEPA filters were invented in America and through engineering and rigorous testing in America we have improved the HEPA filters. Carbon is widely used for gas removal however does not work well in humid environments or for formaldehyde so we developed a proprietary treatment to solve these problems.holmes air purifier hap 675 To ensure the highest quality and safety we make our air purifiers in America.air purifier tampines mall We are focused on improving the most important part of your life - protecting the health for you and your family.quantum pure aire ozone air purifier Average Energy Savings: $142/year How do you build the ultimate air-cleaning machine for allergies and asthma?

you combine the best filters with the best fan and make it in the USA. As allergy and asthma sufferers ourselves, we built the air purifier that we would want to use. Turn your room into a cleanroom! The difference between this purifier and the Ultra is that this air purifier uses a carbon pre-filter for light odors and dust whereas the Ultra does not have any carbon. This air purifier has two filters – a 4” deep carbon pre-filter and a 12” deep main filter. Better than HEPA (99.99%+ at 0.3 microns) Main filter has 4-39X more filter media - lasts longer and quieter The main filter is the same industrial filter that is trusted by hospitals and removes much more than any true HEPA filter. It has 195 sq feet of filter media and that is more than 4 times our closest competitor and up to 39 times what other air purifiers have. Most HEPA air purifiers have a thin filter and while marketed as HEPA they do not achieve HEPA performance. We have tested just about every filter that is out there and haven't found one that can meet this standard.

This is important because they are not as effective in removing the smallest sized particles which are the one's that stay suspended in the air the longest and get breathed deep into your lungs. To remove these particulates an industrial grade filter is required, the more filter media the better. Having more filter media means the main filter will last longer (3+ years) and it creates less air resistance. By not having to work as hard the motor can spin at a slower, quieter rate. These are the same filters used in Hospital Operating Rooms, Clean Rooms, the Nuclear Industry, Containment units, Laboratories, and Pharmaceuticals. Filters are custom sized and made by the only company in the US that makes its own HEPA media. Erik has the best, latest German engineered EC motor and fan so it provides higher air flow while being quieter and using much less power. The EC motor is a much-improved technology over the traditional AC motor that nearly every other air purifier uses.

AC motors use technology that was developed in the 1800’s and use more energy, can have an annoying hum, and are not as reliable. They are common because they are very inexpensive to produce. EC (Electrically Commutated) motors use electronics to convert the AC voltage to DC to run the motor. EC is the latest technology innovation whereas AC motors use technology from nearly 200 years ago. With an AC motor from China, chances are that the copper was wound by hand and the ball bearings are of low quality making it unreliable. EC motors are DC so they are more efficient and use up to 90% less power and in the long term can provide significant cost savings. Runs cooler so greater reliability. Has a proven track record in the telecomm and computer industry. No motor hum that you get with an AC motor Why does the motor/fan start and stop more slowly than an AC motor? EC motors have a soft start programmed into the motor to limit the start-up current the motor draws (there are electronics built into the motor).

The ramp down after power is removed is only a function of the inertia of the fan and the friction of the bearing system. A high quality bearing system will take longer to slow down and stop since the friction is minimized (alignment is better, lubricant is better, etc.). The humming noise comes from the fact that it is an AC motor and all the magnetics are changing intensity at the line frequency. When rotating, these forces are aligned so as to rotate the rotor. When the motor is not rotating or rotating at a speed lower than synchronous speed, they tend to make things vibrate back and forth and that makes the humming sound. If you have an AC motor that starts slowly, the humming starts louder and decreases as the rotor and field come into sync. This vibration is caused by magnetic flux through the core laminations. Known as magnetostriction, (a property of ferromagnetic materials that causes them to change their shape or dimensions during the process of magnetization,) its effect changes lamination dimensions... twice per cycle of magnetization.

This dimensional change, although quite small, produces "sound" characterized as "hum."
