No Filters to Replace. Proven to be Safe & Effective.

Just wipe clean the metal collector plates when dirty. You'll be amazed by how much is removed from the air! (Right)

Most Effective Way to Destroy Harmful Micro-Organisms. No air purification technology is more effective than a germicidal UV lamp when it comes to destroying germs, viruses, bacteria and fungi (such as mold), which can lead to illness.

Circulates air-cleaning negative ions. Found by the U.S. Dept. of Agriculture to be 99% effective against airborne dust & particles.

Proven Performance - Nearly 100% Effective in Clinical Particle Removal Tests.
Achieved a 99.5% removal rate of particles in a large chamber. This is not just hype, as test results are patter00ned closely after real-world conditions.

No Replacement Costs. Just wipe off the metal collector grid. Saves you hundreds in replacement filters over the life of the unit.

The built-in, independently-controlled fan effectively moves the air, increasing air-cleaning efficiency.

Costs Just Pennies a Day to Operate. Uses less electricity than a light bulb, saving you hundreds more over the life of the unit, compared to most air purifiers.

Whisper Quiet. The HF-210 is quiet, especially if the fan is turned "off".

  • Advanced air-cleaning capacity: The electrostatically-charged dust-collection plates magnetically trap pollutants.
  • Germicidal UV Light: Destroys micro-organisms such as germs, viruses and bacteria and helps create a healthier environment.
  • Independently controlled booster fan: Turned on during the day to increase distribution of ions and to turn off at night for silent operation.
  • Voltage & Power consumption: 100-120 VAC, 60Hz Adapter & 8 Watts
  • Coverage area: The unit covers up to 500 ft² (46 m²)
  • Dimensions: L: 13.8" (35 cm) x W: 8.6" (21.8 cm) x H: 5.0" (12.7 cm)


Strange smell from the unit

The HF 210UV produces ozone only as a byproduct of the needlepoint ionization, creating only moderate and safe levels. Depending on the size of the room, and the ventilation, it will produce about 0.015 to 0.04 ppm (parts per million) of ozone, which is well within FDA and OSHA standards.

The best way to remedy a strong ozone smell is to somehow increase air flow near or around the unit, or place it in a more open area, where there is a better air current. Examples can include turning on a ceiling fan, temporarily opening a window, and opening the door to the room. It may become necessary to run the unit on low, since the space may be small enough that it does not require the continuous use of the unit.

Cannot turn on the unit

When removing the collector plates or the back panel for periodic cleaning, please note that they must be returned to the unit in exactly the same position for a flush fit. Reversing the position will result in an incomplete closure and the unit will not function properly.

Unit is making a zapping or hissing noise

This is simply a sign that the dust collection plate and the ionizer needlepoints need 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.

How it works

1. Germicidal UV Lamp.
The air first sweeps past the germicidal ultraviolet light after entering the air inlet. The UV light is lethal against harmful, airborne micro-organisms such as germs, viruses, bacteria and fungi (such as mycotoxins from mold).


Particles & pollutants being drawn over
the electrostatically-charged plates.

2. Collects Particles & Pollutants.
Airborne particles and pollutants are magnetically attracted to the metal dust collection plates, like a magnet. The built in fan, along with the electronic breeze, draw pollutants through the unit and its magnetically-charged plates. Then, you simply wipe the plates clean periodically, removing them from the environment. When the metal dust collection plates become full of particulate and residue, simply wipe them off with a damp cloth. Then, dry the plates and reinsert. It's that easy. The amount of contamination collected by the rag will give you and idea of how much airborne pollution is being removed. You Can Really See the Difference! Simply wipe the plates clean whenever

Trillions of air-cleaning ions are
dispersed through the air outlet.

Negative ions travel throughout the
room, attacking and neutralizing
airborne pollutants.

Studies Proving the Effectiveness of Negative Ion Generators

U.S. Dept. of Agriculture

The U.S.D.A. discovered the following in recent studies conducted in a poultry house, which are notoriously polluted:

  • Reduced salmonella (bacteria) transmission between chicks by 98%.
  • Reduced airborne salmonella (bacteria) by 95%.
  • Reduced airborne dust & particles by 99% in 60 seconds.

(Summary of Study from USDA Website)

Journal of Hygiene
This scientific publication reports that negative ions cause dust particles to agglomerate and settle out of air. For this same reason, ionization can improve the efficiency of filters.

Good Housekeeping Magazine
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.

Journal of Hygiene
Scientists showed that ionization reduced bacterial levels in burns and plastic surgery units by over 96% after a two week period, which results in much better and more rapid healing of patients.

Columbia University
Researchers found people with winter and chronic depression show that negative ion generators relieve depression as much as antidepressants. It was also determined that there are relatively no side effects.

European Respiratory Journal
A statistically significant decrease of carbon monoxide values was found with an ionizer activated. This was discovered by researchers at Brompton Hospital in London, and published in European Respiratory Journal.

Journal of Applied Microbiology
The use of negative ions was even found by scientists to reduce the presence of airborne viruses by about 40%. A study featured in the 1987 issue also showed the negative ions are free from any adverse side effects.

St. James University Hospital
Researchers have found that hospital-acquired infections among patients in the Intensive Care Unit were dramatically reduced when ionizers were introduced - and have remained so since. The ionizers were found to successfully remove bacteria from air, reducing the transmission of infection.

A 1976 study featured in this publication provided evidence that negative ions can have a biologically lethal effect on airborne microorganisms.

Journal of Hygiene
A 1979 study found that using negative ionization in the air protected chickens from airborne infection of the deadly Newcastle Disease Virus.

Journal of Food Protection
A 2001 study found that airborne negative ionization was highly effective at destroying airborne and surface salmonella.

University of Medicine and Pharmacy (Romania)
A test on male rats showed that just moderate levels of negative ions increased the resistance of the rats, reducing or eliminating the effect of some chemicals.

How Negative Ions Purify the Air

Virtually all particles in the air have a positive charge, while negative ions have a negative charge. In which case, negative ions and particles magnetically attract to one another. When there is a high enough concentration of negative ions in the air, they will attract to floating particles in large numbers. This causes the particle to become too heavy to remain airborne. As a result, the particle will fall out of the air, preventing it from being inhaled into the respiratory tract where it can trigger breathing and health problems.

The ionized particle will then be collected by normal cleaning activities, such as vacuuming or dusting. If the particle happens to be kicked back up into the air again, it will be ionized, and quickly settled out of the air once again.

In nature, negative ions are generated by processes such as sunlight, lightening, waves from the ocean, and from waterfalls. "Concrete Jungles" minimize the natural production of negative ions by disrupting the delicate electrical balance between the atmosphere and the earth. Heaven Fresh Ionizer/Purifiers recreate them with electrode pins ("needlepoints") to electrically produce negative ions. This method produces a density that is many times higher than the negative ion level found at Niagara Falls, the highest natural producer of negative ions and one of the healthiest environments in the world.

Cleaning and Maintenance

1- Cleaning the Dust Collection Plates

The dust collection plates should be cleaned about every 20-30 days, or when covered with dirt and residue. Cleaning the dust collection plates is very simple. First, twist the knob on the right hand side of the air purifier and pull the plates out. Second, wipe the plates off with a damp cloth. If there is difficult-to-remove residue on the plate, you should use a mild household cleaner, such as detergent, to help remove it. Third, dry the plates. Fourth, reinsert the plates back into the air purifier. Twist the handle to lock them in place and so that the unit will operate again. Please refer to the lock and unlock symbols on the handle of dust collection plate.

Note: When removing the collector plates for periodic cleaning, please note that it must be returned to the unit in exactly the same position for a flush fit. Reversing the position will result in an incomplete closure and the unit will not function properly.

2- Maintenance of the Negative Ion-Producing Electrodes (Needlepoints)

Periodically, enough dust and particulate will accumulate on the tips of each pin, potentially weakening the performance of the air purifier. Every 2-3 months or if the HF 210UV starts making a loud hissing sound, zapping sound, or seems to be "sputtering", follow the instructions below to clean off the tips of each pin.

2.1- Light dust coverage cleaning:

There are two flexible scraping pads at the end of dust collection plate. When you unlock and pull out the dust-collection plates, these two scrapers will brush against the ends of each pin, removing the dust and particulate. Repeat this process multiple times as needed.

2.2- Heavy dust coverage cleaning:

Ionizer pins can also be cleaned thoroughly by removing the back panel which can be removed by pressing gently at the two arrow points and pulling in outward direction. The Stainless Steel bar with the ionizer pins in the front can be cleaned by using a brush preferably dipped in rubbing alcohol.

Note: When removing the back panel for periodic cleaning, please note that it must be returned to the unit in exactly the same position for a flush fit. Reversing the position will result in an incomplete closure and the unit will not function properly.

3- Cleaning the front grill

If the front grill has collected enough dust, the unit can generate sparks. The situation like this arises when Negative Ions generated by the needlepoints gets blocked by the dust collected on the front grill. To avoid this kind of situation, make sure the front grill has no visible sign of dust particles. If there is dust, then use a cleaning brush or a vacuum cleaner and remove the dust.

4- Replacing the UV Bulb

  • Turn the unit off and open the back cover.
  • Remove the expired UV lamp and replace it with the new UV lamp. Handle the UV lamp on each end in order to avoid breaking the lamp.
  • Press the lamp into the UV lamp slot, so that the metal pins at each end of the UV bulb are firmly in contact with the metal conductors inside each clamp.
  • Put the back cover back on. The air purifier is now ready for operation again.

5- Cleaning the Interior of the Purifier

After removing the back panel, Interior can also be cleaned by using a duster or a blower. Dust particles could also accumulate near the fan and if not regularly cleaned, could cause unit to malfunction. Use brush or blower to remove dust around the fan.

About UV Light Air Purification

Research Studies and Facts

No other air purification is more effective at neutralizing micro-organisms than ultraviolet light radiation.

How Ultraviolet Light Works

Ultraviolet light possesses just the right amount of energy to break organic molecular bonds. As micro-organisms pass by the UV rays radiated from the ultraviolet lamp, this bond breakage translates into cellular or genetic damage for micro-organisms, such as germs, viruses, bacteria, fungi (like molds), etc. This results in the destruction of the micro-organisms.

UV Light Air Purifier Facts & Studies
  • The Centers of Disease Control (CDC) recommends the use of ultraviolet light.
  • The U.S. government now specifies that UV light should be used in air handling units to improve indoor air quality in government buildings, by controlling airborne and surface microbial growth.
  • The Air Institute of Respiratory Education suggests UV lights be used in buildings for indoor air quality purposes, and states that may be the final line of defense against those diseases that have developed resistance to drugs, such as tuberculosis and others.
  • According to the Aerobiological Engineering Dept. at Penn State University, the ultraviolet component of sunlight is the main reason microbes die in the outdoor air. The die-off rate in the outdoors varies from one pathogen to another, but can be anywhere from a few seconds to a few minutes for a 90-99% kill of viruses or contagious bacteria.
  • The Centers of Disease Control (CDC) recommends UV lights in homeless shelters to prevent the spread of disease, particularly TB (tuberculosis).
  • A study by Air & Waste Management Association found the combination of a HEPA air filter and germicidal UV lamp reduced bacteria by 80% in a 3072 cubic foot chamber.
UV Light Air Purification Research Study

UV Lamps Reduce Worker Sickness

This study tested 771 employees in three different office buildings. The UV lights, which were installed in the ventilation system, were operated in three cycles of four weeks on, twelve weeks off. Measurements showed a 99% reduction of germs on irradiated surfaces inside the ventilation system.

During some weeks, there was a 40% reduction in respiratory symptoms, and a 30% reduction in mucous problems in individuals examined. When the lights were activated, muscle complaints among nonsmokers were reduced by 50%, and work-related breathing problems decreased by 60%.
