Q: Why it has two layers of filters?
A: There are two main pollutants in the air. One is micro-meter air particulates. These air particulates’ sizes are around 0.3 to 10 µM, PM 2.5, for example, refers to the air particulate with the size of around µM. The other is the fume pollutants that their sizes are in the nano-meter range. HEPA filter is to clean up the air particulates in the µM range (particulates in the range of PM2.5 and below have already proven to be most harmful to our health); and, the activated charcoal filter is to suck up the toxic gases, not just formaldehyde, but also virtually every type of gaseous compound.

HEPA Filter Dimensions

All measurements are in millimeter.

Q: What is the circulation capacity of this air cleaner?
A: The measured air velocity from the outlet is about 3.7m / sec. The air volume is calculated to be around 0.09 x 0.09 x 3600 x 1.7 = 49.6 Cubic Meters per hour. It is about the 10 times the air volume of average desktop air cleaners!

Q: Why is the HEPA and Activated Charcoal filters thicker than normal?
A: The HEPA filter is folded in design with an aim to increase the contact surface so as to lower the air resistance, as the air resistance is inversely proportional to the total contact surface of the filter. Similarly, the Activated Charcoal filter is thicker to increase the contact surface so as to neutralize the harmful fumes more effectively.

Q: How many speeds are there?
A: There are two speeds: High and Low.

Q: What is the operating voltage?
A: 12v DC. Therefore, you can use it in the vehicle with 12v adapter or on your desk in the office.

A: Very simple, when you notice the HEPA filter has already darken significantly in and out. How long to take for the HEPA to darken thoroughly? it depends on the levels of pollution in your car or in your working/living space. For filter replacements please contact: Nutrimax Wellness @ 62922991.

HEPA Filter Before & After

The filter (left) above has been in service for around 240 hours in a room that is close to street traffic in Singapore.

Q: How long is the warranty?
A: 3 months from the date of purchase with one to one exchange, provided no evidence of abuse (immerse in the water, unit has been dismantled etc). It is nothing much to go wrong. The fan unit is from Taiwan, it is very quiet and reliable.

Q: What is HEPA filter?
A: HEPA filters trap small particles in the air. A good quality filter have uniform pleats to give each one the same filtration efficiency. If the pleats are too close together they may actually restrict the air flow and less efficient in removing fine particles.

There are drawbacks to relying totally on a HEPA filter to purify the air in your home or office. They cannot capture any particles that are smaller than 0.3 microns and do not treat such things as gases, odors and viruses (activated charcoal filter has this function). Because the air must pass through a filter, it is hard to purify the air in a large room with an air cleaner of modest size.
