FAQs

What health problems are associated with bedroom and office air pollution?

Airborne pollutants are acknowledged stressors for people with allergies and asthma. The pollution levels matter, but allergic attacks also depend on the pollutants themselves. Many asthmatic problems are triggered by specific pollens, by dust mites and their waste byproducts, by pet dander, and by mold. Particles that are 2.5 microns or smaller in diameter are even more deadly, as they have been positively linked to cardiovascular diseases. Called PM2.5, these ultra-tiny pollutants enter the blood stream through the lungs. Diesel and coal fuels are notable PM2.5 sources; consequently, people who live downwind from freeways, power plants, and large ports have higher incidences of pollution-related diseases.

Why should I have a Silent Night in my bedroom and in my children’s bedrooms?

Adults spend about seven hours per day in bedrooms and children spend ten. Indeed, we breathe bedroom air for a third of our lives. The pollutants include dust, pollen, pet dander, mold spores, dust mite contaminants, aerosolized particles from hair spray, smoke, bacteria, viruses, and more. Dust is “puffed” into the air each time we move around on our mattresses or walk across our carpets. However, as air passes through a Silent Night unit, it emerges in an ultra-pure state, with up to 12,000 cubic of processing per hour. No filter can stop us from “puffing” up new pollutants from our bedding or from breathing in dander when we cuddle our pets, but Silent Night does the best job possible at a low operational cost. Each occupant of a Silent Night room will breathe in billions fewer of airborne particulate in the course of a year.

Does Silent Night use the HEPA technology that was recommended by my doctor?

ZEPA is better and less expensive. Let us explain. HEPA stands for High Efficiency Particulate Arrestment. It emerged in the 1940s to clean the air in labs where scientists were secretly developing the atom bomb. It is a physical filter, which means the air flows through a thick fibrous mat that blocks the pollutants physically. The air filter in your car (repair techs show it to you and ask if you want a new one) uses this process through a composite of paper. Silent Night’s ZEPA filtration captures pollutants ElectroDynamically as ionized micro-particles flow through its structure. In side-by-side testing, ZEPA out-performs HEPA and confers five advantages. (1) Being less dense, the ZEPA uses less power (excellent economy). (2) Silent Night’s ion engine does not make any blasting fan noise. (3) ZEPA filters are less expensive. (4) Dirty filters do not allow as much blow-through pollution. (5) For equal effectiveness, Silent Night is less expensive to buy.

Why can’t I feel more air flow?

Flow from a six inch diameter fan emits air from 28 square inches. Silent Night’s gradual flow—up to 12,000 cubic feet of air per hour—moves through the full frontal area of 110 square inches. In other words, the same amount of air would blow at only one-fourth the rate. In addition to silence, the added benefit is that Silent Night does not stir up pollutants from carpets and furnishings.

If Silent Night has no fan, how does it work?

Silent Night’s ion-drive engine accelerates air with ElectroDynamic force (the attraction of negatively charged ionized molecules through a positively charged acceleration cage). This silent and efficient process creates a non-turbulent laminar air flow.

Silent Night’s filters seem very porous. How do they capture pollutants?

Silent Night’s ZEPA filters attract the moving particulate ElectroDynamically. Its gradual air flow is important. The air must have sufficient “residence time” within the depth of each filter to achieve its high capture efficiency. It is only a fraction of a second, but for molecules, that is sufficient. A blasting fan would not produce equal results.

Should I turn off Silent Night when I go to work?

Silent Night is designed to run 24/7. However, you can turn it off while you are away for work and save a little on your power bill. This might also extend the life of your filters. For best nighttime results turn it back on at least an hour before bedtime.

Will Silent Night work in a hotel room?

Absolutely! Being lightweight and compact, it is travel friendly. Silent Night’s wall transformer works in all countries, hotels, and cruise ships. Depending on where you are, a simple adapter might be needed to make the plug fit.

Will Silent Night work in China?

Silent Night is compatible with the 220V power system in Hong Kong and China (more than 100 countries use 220V). It is also compatible with the 110-120V power in Taiwan and North America, with the 100V power in Japan, and the 230V power in Russia and other countries. In other words, it is power compatible everywhere. The second answer has to do with the extreme pollution that is experienced about 200 days a year in Beijing, Shanghai, and 50 other industrial cities in China. Two bad days in Beijing would be like six months in Los Angeles, Houston, or New York City. Silent Night will work but it might become overloaded within a week.

Is Silent Night good for my pets?

We received two poignant letters from a customer in California: “One night our 10-year old Havanese dog kept whimpering at bedtime for no apparent reason. Could she be missing the Silent Night which I had moved to another room? Sure enough, when I put it back near her bed she closed her eyes and peacefully went to sleep.” A follow-up note informed us, “Havana passed away quietly. We prepared her favorite bed and blanket, said our goodbyes, and told her how good she was. We now have a puppy named Crickett. We are sure she will like the Silent Night just as much as Havana did.”

Sometimes my Silent Night makes snapping or crackling noises. What does that mean?

Millions of micro-particles pass through Silent Night each hour. Inevitably, some of these adhere to the air engine’s acceleration wires. Most are discharged quietly. Some make a small static snap that is just barely audible. In certain pollution situations the snaps become more numerous and sound like crackles. Yes, some people are reminded of Rice Krispies cereal. If these noises become an annoyance, they can be cleaned away by inverting the machine six times in succession. Small glass beads will slide up and down the acceleration wires and scrub them clean.

Can this product cause graywall?

Any source of negative ionization can cause dust particles to stick to a positively charged wall (or other surface), so yes. This effect might not be noticed right away because it is light and dusty-colored. If you see it, move your Silent Night further from the wall. In most homes, 12 inches is enough. In any case, do not put your Silent Night closer than 12 inches from a wall or computer. Graywall might result.
