How does the ultraviolet light in the WAVE Air Purifier kill both biological and chemical contaminants?

WAVE Air Purifier uses a “J” Lamp that produces UVC and UVV light (both wavelengths are fused into the Lamp). UV-C is a short-wave radiation: it attacks the DNA of the cell. This wavelength primary uses are for the destruction of bacteria, viruses, mold and other microorganisms that pass through the Aluminum Reflector Tube. The Centers of Disease Control recommends this method for destroying viruses such as tuberculosis. UV-V is primarily used for oxidation; this is the portion of the lamp that will destroy chemicals and odors such as cigarette smoke, VOC’s, aerosols cleaning solvents and formaldehyde.

What does the unit do to viruses?

A WAVE UV Air Purifier will destroy biological contaminants which include all types of viruses by attacking the DNA of the cell and destroying it. It will also destroy mold spores, dust mites, pollen, and bacteria viruses and musty odors. The WAVE Air Purifier has the capacity to eradicate biological contaminants but the effectiveness depends on the amount of time it operates and the ability for the contaminated air to travel through the unit.

How much electricity does a WAVE Air Purifier consume?

The Whole House Unit uses 37 watts of electricity. The Portable Unit uses 50 watts of electricity.

Does a WAVE Air Purifier have to run 24 hours a day?

The in-duct model is designed to run 24 hours a day. That is not to say that it will. The in-duct model has a sensor that allows the air purifier to run only when the fan is on. In times when the air handler is not on it is recommended to run the fan for 2 hours. When conditions arise such as the presence of odors or chemicals, you can increase the operation time for an additional hour or as needed. With the portable unit you can operate it for an hour a day or increase the time depending on conditions. You can the easily move it to another room.

Does a WAVE Air Purifier produce ozone?

As part of the WAVE process involved in UV air treatment, the UVV (187 nm) portion of the lamp is fused to the UVC (254 nm) portion of the glass. WAVE lamps are not ozone generators; ozone is a bi-product of oxidation. As the oxidation is emitted from the UVV portion of the Lamp, the UVC wavelength immediately starts to break down residual ozone that may be present. WAVE Air Purifiers are treating the chemical contaminants in the air at that moment in time; this is one of the components of its patent. The amount of residual ozone produced by a WAVE Air Purifier with the UVC/UVV “J” lamp has been measured by independent accredited testing laboratories and found not to exceed 0.0035 parts per million at the outlet of the purifier. This is less than 1/10th of the ASHRAE limit (0.05 ppm) and less than 1/20th of the OSHA (0.10 ppm) standards for safe ozone levels. In fact, the UV process produces less residual ozone than a photocopier or the arcing from an electronic air cleaner, and in documented air quality tests, zero ozone levels have been found in the living or working area.


What is WAVE Ventilation?

WAVE Ventilation solves the century old problem of excess moisture by utilizing controlled and targeted ventilation as opposed to a conventional dehumidifier which removes moisture particles from the air by condensation and then re circulates the same stale air back into the room. WAVE ventilation focuses in on the major source of moisture problems which is the lowest point in a house where there is the most moisture infiltration, stagnation and condensation; namely the basement and crawl space. The unit entirely expels the cool damp air out of the house and uses the warmer and fresher upstairs air to effectively lower relative humidity and dry out the structure. It creates an air exchange in the entire house that will reduce moisture related problems such as excess humidity, a musty basement, mildew, and alleviate conditions that aggravate asthma and allergies.

What about energy factors – expelling air conditioned air in the summer or heated air in the winter?

It is a scientific fact that it is less costly to heat or air condition a drier home than a damp one. The drier environment will have the benefit of increasing the efficiencies and performance results of the heating and air conditioning units. A test conducted by the Department of Energy compared homes with spaces that had foundation vents versus those that had mechanical ventilation, closed foundation vents and replenishment air from the upper levels (identical to the Wave ventilation technology).The results showed that relative humidity was in the 60% range with mechanical ventilation as opposed to 79% range with foundation vents. The overall energy costs to heat and cool the entire home was 17% less KWH usage in the drier homes with mechanical ventilation as opposed to those with the foundation vents.

How does the unit affect airflow?

The majority of homes are not airtight. There is enough air flowing from the doors, windows and openings. Air pressure and flow can be affected by any combustible appliance (i.e. furnace, gas dryer) or ventilation unit (i.e. bathroom fan, attic fan). We therefore recommend that the WAVE ventilation be installed at least 10 ft. away from any furnace in order not to interfere with the air flow. In an extreme airtight situation and in conjunction with other high capacity ventilation and combustion appliances, we have a passive fresh air ventilator kit ASV 90-4. It requires a 4" hole to the outdoors that delivers filtered air to a room and is equipped with a manual damper.

Will it work for the entire house?

If you have moisture problems, your top priority is to expel it. A conventional basement dehumidifier just won't do it. In the summer, if the air conditioning is working upstairs; the drier replacement air that comes from upstairs, accomplishes the goal of a dehumidified basement even faster. If the air conditioning is not working, then the air coming from the upstairs is warmer than downstairs, and will then raise the dew point and reduce the condensation. There is a negligible increase in utility costs when running the air conditioning, especially when you spread the cost over a full year. In the winter, the moist air is expelled and the warmer air replacing it is drier and a lot easier and less expensive to heat. WAVE ventilation only uses 40 watts of electricity- similar to a light bulb! The pay back is less than two years, just in the savings from reduced electricity costs, in comparison to a dehumidifier. Overall it is less costly to heat or air condition a drier home than a damp one.

How does it work in the summer and winter?

In the summer, when there is no air conditioning in the upper levels, the warmer air flows downstairs raising the temperature, which lowers the relative humidity and raises the dew point resulting in less condensation. When there is air conditioning upstairs, the natural dehumidifying properties of the conditioned air comes down and lowers the relative humidity. The downstairs is drier, warmer and without any basement odor. In the winter heating season, water will condense on windows and walls because the moisture inside hits a cold surface. After the WAVE ventilation is operational, the moisture upstairs, flows downwards and the windows dry up. The unit raises the temperature downstairs and draws out saturated moisture in the structure. The drier air is easier to heat than the heavy moist air, thereby saving money in heating bills. Also, heat loss is minimal because cold air is always at the floor level. In the winter the unit will generally operate at a lower speed due to the fact that heat evaporates indoor moisture.

How will it improve air quality and help cure Sick Home Syndrome?

The air in many homes contains harmful pollutants that are invisible, odorless and not readily detected. These substances can be more detrimental than the air outside and can cause health problems such as irritated eyes and nose, headaches, dizziness, tiredness, infections and respiratory diseases. When windows and doors are closed, the house cannot breathe and rid itself of these elements. Moisture further aggravates the condition, by having the capacity to trap and contain these contaminants. Moisture is a source of nutrition for molds, dust mites and other infestation that are primary triggers for asthma and allergic symptoms. WAVE ventilation provides both moisture control and improved indoor air quality on a continuous basis without any maintenance or complicated controls, thereby insuring a healthy environment. By exchanging the damp polluted air several times a day, you are transforming the home into a fresher, drier and healthier environment.

What model do I need?

The unit that you get obviously depends on the type of home that you occupy and the size of the room that in which the unit will be placed. Please take a look at the specific model pages to help better determine which unit is right for your living conditions. Basement Models Crawl Space Models Slab Homes/Condo/Apartment Model.

Where and how is it installed?

We recommend using a professional to install the WAVE Ventilation unit and we have a network of approved installers, but handy individuals can certainly install it themselves. In either case though, it is extremely important to install the unit as per company specifications, to maximize ventilation and moisture control. It requires a dedicated 6" vent to the outside and is located in the lowest part of the home, in an area where it will be able to draw in the most moisture and create a strong airflow over the maximum surface area. The installer will place a passive air register in the floor or door upstairs (when there is no open stairwell), to allow for a fresh, drier and warmer replenishment air to enter the basement while the WAVE ventilation is expelling the moist air. Additional passive vents at the floor level in doors or partitions may be required to facilitate the air flow freely throughout the entire level. The proper installation is crucial in order to dry out the structure and prevent moisture from stagnating, condensing and saturating the structure.

How quickly should I expect to see results?

The WAVE ventilation solution is a drying out process that will vary in time depending on home, environment and conditions. The majority of homeowners will see results relatively quickly ranging from within a few days to a few short weeks. In extreme conditions and when there may be heavy moisture saturation in the structure, we recommend that you allow the unit to dry out the basement, for as long as it takes. For the home environment to improve, contributing sources of moisture from water seepage should be remedied first in order to allow for the basement to dry out. After remedying the water problems and installing the WAVE ventilation you should start to see improvement, although again, each home situation is different.

Is there a guarantee and warranty on the Iron 300X and Wellmaxx?

Both systems carry an unmatched one year performance guarantee and a 1 year manufacturer’s warranty on parts.

What are some of the features that differentiate the O2Hydro from the competition?

The mass transfer tube which oxidizes the water in real time, provides for more surface contact, and creates a “scrubbing” which causes the air bubbles to continuously move throughout the water. The O2Hydro’s aeration tank is just as large as the media tank, which again, allows for more effective aeration. The proprietary depth filtration package automatically resettles and layers properly after backwashing. The media get 100% bed expansion during backwashing so that they are thoroughly backwashed and cleaned. The O2Hydro contains a built in bypass system and a customizable post filter.

How does the system backwash itself?

Just set the timer on the control head for the desired time to backwash and the O2Hydro will automatically backwash itself at that specific time.

How does the O2Hydro know when to turn on/off?

The O2Hydro contains a flow switch which automatically activates the air pump when there is a demand for water in the house and shuts off the air pump once water has stopped flowing. This allows for oxidation in real time.

What are the most important factors in the aeration process?

The more surface contact there is with the air bubbles the more effective the aeration process. Through the use of the mass transfer tube, the O2Hydro injects countless, micro air bubbles into the water in real time so there is an abundant amount of surface area for the aeration process to be highly effective. Utilizing extremely small bubbles increases the rate of gas transfer (aeration) due to the higher contact surface area.

What does aeration mean?

Aeration is the process of mixing air into water. The aeration process oxidizes the iron particles and other contaminants within the water so that they can be readily filtered.

What are some of the most common problems with well water?

While private wells are unique and may have specific contaminants; iron, hydrogen sulfide, and manganese are common contaminants present in a predominant number of private wells.

Why buy a whole house filter?

It is extremely important to filter all the water throughout your home as certain contaminants such as chlorine; which has been linked to cancer, and VOCS are easily absorbed through the skin. Water dispensing refrigerators and ice makers also require filtered water. In addition, children have a tendency to drink water from all faucets in the home so you want to be sure to protect them. And of course, there is the convenience of having clean, healthy, great tasting water from every faucet in your home.  

What does the DualPlexx remove from the water?

In an independent lab test, the DualPlexx removed 99% of the chlorine found in the test water supply. It also removes iron, hydrogen sulfide, lead, arsenic, mercury, aluminum, VOCs and THMs. Actual results may vary based on your home's specific water supply. Your water will be healthier, odor free, and will taste great.

Will the DualPlexx work on private well water?

The DualPlexx was designed to filter and purify municipal water only. Well water presents different problems. Check out our solutions for well water. 

Will the DualPlexx remove iron?

The DualPlexx will remove low levels of iron. If your water contains significant amounts of iron, please follow this link see our well water solutions.

How does this system compare to other filtration units?

Coupled with our patented parallel flow design which increases contact time with the media, the DualPlexx delivers superior purification with virtually no loss of pressure. The first filter will remove sediment, iron, and hydrogen sulfide and prevent bacterial and algae growth.

How do I replace the purification media?

To replace the purification media, shut off the water supply to the system. Open a faucet in the house to release pressure from the canisters. Using the plastic wrench included with your system, slowly unscrew the first canister. Keep a pail and towel handy just in case. Remove the inner white canister, unscrew it and replace the old media with your new set. Put the white canister back into the blue one. Apply silicone (included) to the black “O” rings, screw the canister back into the system by hand and tighten with the plastic wrench. Repeat the process for all three canisters.

How often do I need to replace the purification media?

The Dualplexx has an 80,000 gallon capacity but the answer really depends on water usage. We recommend changing the media approximately every 9-12 months. If you notice a change in the taste and look of your water, it is probably time to change the media. Depending on the sediment and iron levels in your water, the stage 1 filter may need to be replaced more often.

Will the Quadmaxx work on private well water?

The Quadmaxx was designed to filter and purify municipal water only. Well water presents different problems. Check out our solutions for well water.

Will the Quadmaxx remove iron?

The Quadmaxx is designed to remove the aforementioned contaminants, and as such is not designed to remove iron on its own as it would clog the purification media, and a pre-filter is required. HydroCare offers a highly effective pre-filter as an addition to the Quadmaxx and can be purchased at checkout.

What is inside each canister?

Each canister contains an identical patented blend of 3 dimensional material which is embedded with superior purification media, all tested and proven to remove a number of contaminants.

Why 4 canisters instead of one?

Through the highly innovative 4 canister design, the Quadmaxx is able to achieve high standards of water purification without loss of water pressure. This unique design also provides the capability to continue to use the Quadmaxx even in the event that one of the canisters gets damaged.

Does the water pass through all 4 canisters?

The inlet water supply is split into four separate flows, each passing through one of the identical canisters. This allows for increased time spent going through the purification media without any drop in water pressure.

How do I replace the purification media?

When the time comes, shut off the water flow into the house and open up a faucet to drain the water in the pipeline. Then remove each canister, push the old media out using the media insertion tool included with the Quadmaxx and dispose. Utilizing the media insertion tool push the replacement media into the canister and then snap the canister back into place. Once all four canisters have been changed, slowly turn on the water supply checking for any leaks. For a visual demonstration please see the video on the bottom left.
