1.What are negative ions?
There are positive and negative charges in the air. Integration of positive charge and ion form positive ions and that of negative charge and ions form negative ions. Too many positive ions will leave you feeling depressed, lethargic, headache and more. Discharge of a high-voltage-exerted pin electrode is able to produce voluminous negative ions. And these negative ions are able to attach themselves to airborne toxins and remove the pollutant from the air.

2.What are the benefits of negative ions?
Remove bacteria, vitalize our cells, increase the oxygen holding capacity of blood, improve metabolism, improve alertnerss, remove fatigue, boost resistance to disease, have a substantial healing effect on headache, insomnia, constipation, allergy, asthma and more.

3. Negative Ion Facts
  • Approved by the U.S. FDA (Food & Drug Admin.) as an approved allergy treatment.
  • Ionization is mandatory in many European and Russian Hospitals.
  • In March of 1999, Good Housekeeping Magazine had its engineers test an ionizer by using a smoke test, and found that it cleared out the smoke in a tank.
  • A recent study by the U.S. Dept. of Agriculture found that ionizing a room led to 52% less dust in the air, and 95% less bacteria in the air (since many of the pollutants found in the air reside on floating dust particles).

4. How do negative ions remove pollutants from the air?

How negative ions workHow negative ions work

Negatively-charged negative ions attach themselves to contaminates and allergens, which are positively-charged. The newly-formed larger particles are then able to fall to the ground, and out of the air we breathe.

Most floating contaminates and allergens are positively charged, and of course, negative ions are negatively charged. In environments where high densities of negative ions exist, they are able to reverse the charge of floating contaminates to a negative charge.

This results in a magnetic attraction among the floating pollutants in the air, causing them to aggregate, or clump together.
As a result, they become too heavy to remain floating in the air, and fall harmlessly to the ground, where they cannot find their way into your respiratory tract.
At this point, even if they are inhaled before falling out of the air, these now larger particles are able to be intercepted by the "filters" of the upper respiratory tract, due to their increased size.
Of course, without a continual generation of negative ions, some of these enlargened pollutants can find their way back into the air. Heaven Fresh air purification systems are designed for continual use, ensuring pollutants stay out of the air you breathe.
Some studies suggest that negative ions also have a biological effect on bacteria and viruses, killing them on contact in many cases.

5. Why negative ions ?
Negative ions are natures most powerful air-cleansing agents. There is nothing in the world more effective in taking allergens and contaminates out of the air we breathe. Unfortunately, due to the tight construction of today's homes and buildings, they are unable to take effect within indoor environments.
Negative ions are created by nature, and found at their most optimal levels where the air is most pure and healthy. These places typically include up in the mountains, near waterfalls, where lightning has just occurred, in open meadows away from "the city", and the ocean shore by the crashing waves.

5) Air Ionizers Wipe Out Hospital Infections by New Scientist

Repeated airborne infections of the bacteria acinetobacter in an intensive care ward have been eliminated by the installation of a negative air ioniser.

6) Benefits of Negative Ions on Liver and Lung Function By U.S.S.R.
The effect of negative air ions (NAI) inhalation by rats on
energy reactions of mitochondria in homogenates of liver and
brain was studied

7)Air ion effects on human performance
The effect of air ions on the human organism has been the subject of much debate. Commercial units are available which claim beneficial effects through the generation of negative air ions into the atmosphere. Conversely, it has been claimed that an excess of positive ions can cause discomfort and symptoms such as headaches and nausea in some people.


8)Negative Ions Create Positive Vibes

May 6, 2002 -- There is something in the air and while it may not be love, some say it is the next best thing -- negative ions. Negative ions are odorless, tasteless, and invisible molecules that we inhale in abundance in certain environments.

6. What is HEPA filter?
HEPA filter also known as High Efficiency Particulate Air Filter usually employs a fan drawing air through a filter. Since it uses fans to filter the air, HEPA filter is usually very noisy and the cost to replace the filter is quite expensive. HEPA air filters can only effectively remove particles of larger than 0.3 microns from our air. And most of the airborne pollutants and irritants are smaller than 0.3. Also, with HEPA filter substantial portion of the airborne particles flowing through our rooms remain unfiltered. Only the air that passes through a HEPA filtering unit is cleaned.


7. How can Heaven Fresh air purifier purify the room without a filter?
We use high amount of negative ions to purify and sanitize the air. We use 16 stainless steel needle point to produce high negative ions and static dust collection plate to clean poisonous gases. Indoor airs usually contain high number of positive ions. And excessive positive ions can cause nausea, bad mood and dizziness. Our air purifier generates high concentration of negative ions to wipe out the excessive & harmful positive ions resulting in a fresh, clean and healthy air.

8. How much is the maintenance cost for Heaven Fresh air purifier?
All our air purifiers only consume 3W to 6W of electricity or equal to 2.5USD to 5USD of electricity per year.
9. Are there any negative effects using Heaven Fresh air purifier?
Since Heaven Fresh purifier is negative ion air purifier, it does not present any negative side effect. You will only live more healthy with our air purifiers.


10. How does Heaven Fresh air purifier compare in cost to the other air purifier?
Heaven Fresh air purifiers are much more economical yet more effective compare to other air purifiers. Heaven Fresh air purifiers can clean the air thoroughly with much cheaper price.


11. What is Black Wall or Gray Wall Effect?
Gray wall or Black wall effect is a situation where the dirt particles and black residue near the needle are electro-plated or built up to the wall. As a result, it will be hard to clean the air purifier.


12.Does Heaven Fresh air purifier have Black Wall effect?
Heaven Fresh air purifiers use the stainless steel needle point that is corrosion free. And the collector plate is made of highly conducive materials that will attract ionized particle. The ionized particle will only attach to the metal collection surface not the low conducive materials around the machine, cover or on the wall. So The Black Wall or Gray Wall effect will not occur on our air purifiers.

13. Does Heaven Fresh air purifier produce noise?
Our air purifiers feature virtually silent operation and noiseless design. Heaven Fresh air purifiers do not utilize fans that can cause serious noise pollution like the HEPA filter.


14. How much is the maintenance cost for Heaven Fresh air purifier?
No maintenance cost is necessary. The only maintenance needed is unit cleaning. Simply open the units, wipe off the dust on collector plate and the needlepoints every one or two months. And then clean the circuit inside the unit every six months.

15. How do I choose the right air purifier for my room?
Choose the best air-purifier according to your square footage, level of air contamination, odor levels and air circulation to get the maximum effectiveness and to be safe/healthy.

17. Easy maintenance of XJ-2000Maintenance (Make Sure Unit is Unplugged Before Performing Any Maintenance!)

Cleaning the Dust Collection Plate The dust collection plate should be cleaned about every 20-30 days. If the purifier begins making a zapping sound, then this is simply a sign that the dust collection plate needs to be wiped off. The zapping sound is just a result of a significant amount of dust build-up on the collection plate, which results in a static charge between the dust on the collector, and one of the ion-producing electrodes. Cleaning the dust collection plate is very simple to do. You just need to loosen the two screws that hold the dust collection plate in. Then you just need to pull the dust collection plate out, and wipe it off with a damp cloth. You should then wipe it off with a dry towel, and reinsert it back into its slot. If there is difficult-to-remove residue on the plate, you should use a household cleaner, such as ammonia or bleach, to help remove it.

dirty dust collection plate loosen the two screws wipe off dust collection plate

Maintenance of the Negative Ion-Producing Electrodes (Needlepoints)Every 1-3 months, or if the unit stops working or begins making noise, the dust and particulate should be wiped off from the ends of each of the needlepoints inside the front grill of the unit. First, make sure that the unit is unplugged. Next, remove the collector plate (see the photo above). Now, the needlepoints will be accessible through the opening left by the removal of the collector plate. To clean the needlepoints, either wipe off the dust with your fingers or cloth, or a cotton swab (like Q-tip) dipped in rubbing alcohol.
Cleaning the Interior of the Purifier
The interior of the Heaven Fresh ionizer should be cleaned every 3 to 6 months. First, loosen the four screws at the base of the unit to open the cover of the purifier. It is best to use a Phillips screwdriver with a head that will sufficiently fit the holes at the bottom of the unit. In doing so, you will be able to see the electronic circuitry of the unit. Then, simply and carefully wipe away or blow off any dust that has collected on any of the components. If you use a damp cloth to wipe away the dust, then blow-dry the interior of the air ionizer before replacing the cover and turning the unit on again.
