Fresh Air Odors

Code numbers for alternate RCI cells shown after this article.

 

 

Allen Johnston provides the following technical information (with a field perspective provided by Bob Giddens): 

Bob's best estimate -- I consulted with Larry & Eileen Miller about this -- is that an odor problem comes up about 10% of the time -- sometimes due to ozone, sometimes due to other factors. Ted & Chris Belz (who also handle 500 units per year) say that some people object to ozone, but they (Ted & Chris) haven't found other problems with the Fresh Airs. In other cases, people have ended up with 4 problem units in their Success Packs.

Some Fresh Airs have a lint screen that should be changed (this material is no longer being used). The screen material with a white plastic surface is susceptible to being degraded by the UVX lamp. As the screen degrades, a smell is created. Its intensity ranges from very mild to very offensive.

The company replaces these screens at no cost and they can be easily installed. One screw has to be removed from the center of the back of the unit, then the lint screen housing must be pressed from the sides to unclip it from the unit. The old screen is thrown away. No need to return it to EcoQuest. There is no charge for this repair.

The phone number for Customer Service

is  800-989-2299.  We apologize.

Meanwhile, the units will run with the screen totally removed. So if a problem exists, it can be solved in 5 minutes.

In an environment where there is cigarette smoke, pet dander, litter box smells or cooking grease in the air, the screen is especially important. Install it in the empty housing as soon as the new screen comes in.

Some dealers have an issue (or think they do) with the RCI cell. You can unplug the power to the RCI sell (leaving it installed in the machine) and run the unit is ozone/ion mode only to determine easily if an objectionable smell originates from that source.

I am sorry this troubleshooting matter has become a necessity, but it has. We might as well understand the options and move forward without getting upset.

Let's review the testing steps:

1. If you have a unit with one of the improper lint screens, remove the screen and run the machine with no screen. See if the smell is sweet and fresh. This can be hard to determine in a large area; the evaluation becomes easier if the purifier is in a small bedroom or bathroom for testing purposes. Decide if it smells fresh and wonderful or if it has an offensive dimension to it. Various people have described the problem as a "new car smell," a "burning wire smell" or a "metallic smell." It seems to me that it varies based on the humidity level (more noticeable in dry environments), but we aren't one hundred percent sure. The pollution load (musty home, pets, etc.) would also be a factor.

2. Unplug the RCI cell and run the unit as an ion/ozone air purifier only. Choose a medium setting for your extended test and check out the Away Mode for a few moments.

3. If need be, try 1 alone, 2 alone and 1, 2 at the same time.

If the RCI unit is smelly, order "Low Oxidation" RCI cells. Some people -- especially in California and other places with low humidity -- consider this to be a good interim solution. I view this as a safe course for anyone who is afraid of this problem.

Low Oxidation replacement RCI cells can be ordered for Fresh Airs that put out a strong smell. The replacement cells cost about $11 each, and the old cells (after the swap-out is done) must be returned to EcoQuest.

Keep This Odor Issue In Perspective

I hear complaints from some people about odors. Sales are lost. Prospects become angry and don't even want to consider a solution. This is serious.

Other EcoQuesters don't seem to come up against this problem.

I'm posting these details and procedures in case you encounter this problem. Whether you do or don't, we all have to be prepared. If one of your Business Owners has a problem, refer him or her to this webpage. Some people say the problems are imaginary and a matter of attitude. Having smelled some bad machines myself, I think they are real. Unfortunately, we do not have a handle on this yet.

Corrective Action

Check the lint screens on all units in your possession (and call your customers). If you have screens with white plastic, ask for replacements and put this behind you. Ideally, you should run each unit for 15 minutes to satisfy yourself that it is working right and smelling right.

As to identifying good versus bad screens ... if you have black plastic or honeycomb screens, those are okay. Only screens with white plastic need to be swapped out.

Allen Johnston says, "Units with incorrect screens should NOT be shipped back to the company. The lint screen swap will be sufficient. But we want you to do all the checks before you decide."

What is the Difference between Full Oxidation RCI and Low Oxidation RCI?

 

EcoQuest manufactures 3 different RCI Cells for Fresh Air 2...

 

US70728 (Full Oxidation Cell) -- standard with Fresh Airs in the US.

The bulb in this cell is made from hard quartz glass. Hard quartz allows 185 nanometer (nm) light, the frequency which converts oxygen into ozone, to pass through.  Consequently a Full Oxidation Cell creates ozone.

 

US70852 (Low Oxidation Cell) -- standard with the Fresh Air Everest in the US.

The Low Oxidation Cell has a hybrid bulb. Made from 20% hard quartz and 80% soft quartz glass, it allows a limited amount of 185nm; consequently, it produces 80% less ozone than the full oxidation cell.

 

CA70810 (Canadian Low Oxidation Cell) -- standard for Fresh Air Everest in Canada.

The Canadian Cell contains the full oxidation bulb but it has an inner RCI target, which reduces the ozone level to meet Canadian Government regulations.

 

Is the Low Oxidation Cell as Effective?

The ozone production is lower, and this is more significant than it might appear. In the complex chemistry occurring in and on the RCI cell, the ozone produced by 185nm light is also being broken down by the 254nm light.  When ozone is broken back down into oxygen, other oxidizers are also produced including hydroxyl radicals, OH, super oxides, O2-, and hydrogen peroxide, H2O2. By reducing the ozone production, we also reduce these other oxidizers.

 

Why would I want a Low Oxidation Cell since the Full Oxidation Cell is more powerful?

The reason a business owner or customer would want to use a Low Oxidation Cell would be if the oxidizers coming from the Full Cell were too strong. Some individuals are ultra sensitive to oxidation. For these people, even low levels of ozone and other oxidizers can be offensive.  Experience has shown the Low Oxidation Cell can usually satisfy these customers.

 

Will using the Fresh Air in High Mode (which adds ozone) make up some of the lost effectiveness?

YES! As explained previously, the difference between the cells is ozone output.  Putting the Fresh Air in High Mode turns on the ozone plate. Unlike the UVX bulb, which is either on or off, the plate is adjustable. The ozone created by the plate can make up for some of the reduced ozone production by the bulb and allow the Fresh Air “system” to produce the other oxidizers.

 

Will the Low Oxidation Cell provide similar results as compared to the Full Oxidation Cell?

Many factors come into play. For one thing, every environment is different. Thus, it is impossible to say based solely upon square feet or cubic feet what kind of results can be achieved. Imagine two 20’ x 20’ rooms: one with carpet that has lots of mold and bacteria growing in it and on the furniture -- what we would all call a “dirty” environment; the other with hardwood floors and no mold or bacteria – a “clean” environment.  Both rooms can be effectively cleaned by Fresh Air in normal mode (RCI only); but the “dirty” room might require significantly longer than the “clean” room. The same can be said about the Low Oxidation Cell performance as compared to the Full Cell. The Low Oxidation Cell can in many instances do the job but it will take longer. Also, there reaches a point where the space is too large or too dirty for the Fresh Air to overcome the problem, in which case additional units might be required. There are no absolutes due to all the variables, but the Fresh Air is designed for use in up to 3,000 square feet and typical household environments.

 

Dr. Marsden and Kansas State University recently tested the RCI Cell against several molds and bacteria. Will the Low Oxidation Cell provide the same results as obtained in the University study?

Dr. Marsden and the researchers monitored the ozone level in the chamber and used air exchanges to keep the ozone at 0.02 ppm (less than ˝ of the .05 ppm limit for occupied spaces).  Thus, if your Fresh Air raises the ozone level to 0.02 ppm you can expect similar results. If the area being served is so large that the ozone level falls significant below .02 ppm, the results may not be possible or the time required twill be increased.

 

Here is Dr. Marsden response to the above question: 

"The research showed that when an equilibrium was reached in the Chamber, the RCI technology was effective against all microbiological hazards that were evaluated. In a larger room, the RCI system would also reach an equilibrium, but it may require more time. The system would also have to be designed with adequate capacity.” 

Dr. Jim Marsden, Regent's Distinguished Professor

Kansas State University

It should be noted that although the Kansas State researchers used ozone as the gauge for their test, the RCI cell produces many oxidizers which are much more powerful than ozone alone. It has been documented that the Purifying Plasma coming from an RCI cell inactivates pathogens up to 40 times faster than ozone alone at the same ozone level.

 

Are Fresh Air units available with the Low Oxidation RCI Cell or is the only way to get the cell through exchange?

Yes, and this is a relatively new policy. Here are the item code numbers:
