Question about "DuctwoRx"

Re: Question about \"DuctwoRx\"

Ozone does not eat metals. It might break down rubber etc in high ppm. I do not work for NASA but we do build the space suit at work. This RCI has been around for years on the shuttle as many at work will tell me this.

Maybe BS to you but it worked for NASA and all our clean rooms at work have ozone (oxidizer) and ionization since I have worked there (only 11 years).

I could careless but it works. Just like a UV light or ozone in salt water reef tanks. It works, period.

If you want, email the company and see what happens instead of posting here? Then see what is snake oil or whatever. Next you will say ozone is bad no matter in any ppm......Some people feel the same way with synthetic oils etc. Do what gives you are warm and cozy feeling... /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

Re: Question about \"DuctwoRx\"

Didn't say ozone (O3) is corosive to metals. I asked whether hydrogen peroxide (H2O2), which is what they claim the gizmo makes, is corrosive to aluminum. Well, neutral H2O2 is not corrosive to high puirty aluminum but is incompatible with copper, brass, carbon steel and lead. (http://www.h2o2-4u.com/tech.html). Gee. Copper and lead. Don't see those in any heat exchangers do yah? And I'm shure the Al they use is lab grade, too.

Maybe NASA uses something like this, and ozone is used is a lot of situations. Never said it didn't. What NASA does in a space vehicle or what you do in a clean room is not necesarily in any way shape or form comparable to application or effectiveness in a consumer forced air system with a heat exchanger. I've seen clean rooms dehumidified by massive reccyling dessicant wheels: would this work in a central consumer A/C system?

What I said is, this company doesn't seem to claim this thing specifically does anything. I said show me the third party lab results. People swear by 'magnetic water softeners' and all kinds of other snake oil.

You want to spend your money on this stuff, knock yourself out.

However, you may consider attacking what somebody writes, rather than what you read, which appears to be two different things.

And I know exactly how ozone and UV works as a disinfectant in fish tanks or anything else.

Re: Question about \"DuctwoRx\"

I DO see them on heat exchangers everyday. Heat exchangers for all commercial / military aircraft have them! /forums/images/graemlins/grin.gif

hydrogen peroxide has been used for years in water and air contamination (along with others). Using h202 alone is not as effective as ozone or other chemicals. The weight by volume on this is so small, don’t even worry about it. It is not like 35% to 50% used my many cities. The ozone, at 0.04 MAX would post for most concern.

Again, instead of posted here “step- up to the plate” and email them? . I am noted attacking anything what you write, but how you know it. It is not per TBN policy #2 I believe.

It does not claim anything? I do not know how you read, but I read theses;

#1 “….improving the quality of air passing through your HVAC system.”

#2“…each room will be fresher and every air purifier more effective.”

#3 “….reduces airborne contaminants, and odors…”

#4 "“reduce orders, smoke, and other broad spectrum of indoor air contaminants”

These are in black and white, or electrons form, on there website made to the public; for millions and millions to view!
I think there freshair units are better but they are at a higher price..to high for some.

Call it what you will but they work. I have three dogs in my house and you would never know it! We can cook fish etc and with 30 minutes the complete house smells zero.

Sorry, couldn't let this one pass <font color="blue">Heat exchangers for all commercial / military aircraft have them! </font>
I must have been sleeping during classes on this one. 23+ years in the A/P field.

Re: Question about \"DuctwoRx\"

I see them everyday in the assy room and I did spc on the alu bars (form a core) before dip braze.

Some aircraft that come to mind:
B1, B2
F16
F18
B52
777
767
747
ERJ170

Re: Question about \"DuctwoRx\"

I thought this might be another one of those small ozone generating gizmo's that you see in homes and businesses tucked away on book shelves that are being sold for hefty prices when we read the post. Did I say that more than a few have claimed that ozone isn't the best thing to have in your home even though it is produced by a lightening storm naturally?

When we built our home we installed a UV disinfectant gadget in our return air plenum. It's supposed to freshen the air and since we have two pets we figured what the heck. But when it came time to replace the bulbs a year later and I realized that the set of bulbs was $80.00 I unplugged the device. Couldn't justify the cost of running the unit since we really didn't see any benefit while it was running.

We also have a Honeywell electronic air cleaner coupled to our forced air furnace and I think the UV deal was redundant anyhow.

Junk do you want me to pick one of those UV systems up for you? /forums/images/graemlins/wink.gif

Re: Question about \"DuctwoRx\"

Yes Ozone is bad in high doses. Above 0.05ppm in longer durations is bad. The kicker is that it dissipates so fast that most times you do not worry about it.

Ozone is good and is a excellent for killing mold, mildew, parasites, Bacteria, etc.

I use an electronstatic filer (cost me zero) and you just wash it off! It works good on my furnace (commercial unit).

So the $80 for 1-year was too much; that is $0.22 per day. The problem with UV lights (UV only) is that the flow rate has to be real slow to kill most parasites or bacteria.

The problem with a Honeywell electronic air cleaner is does not kill as much as UV nor does it remove orders. Also does not the Honeywell Electronic Air Cleaners have the Replacement Pre-Filters costing from $25 to $60. To top it off, these pre-filters need to be replaced every 1 to 6 months depending on your lifestyle (such as number of family members, pets, smoking, cooking, woodworking, etc). What about the post filter replacement?

Plus the Honey filter does not remove cig or cegar smoke etc. Smoke in your house and see how long the smell stays in the house. I can smoke a cegar in my basement and my wife does not know.... /forums/images/graemlins/grin.gif

Oh, Honeywell sells Ultraviolet Air Treatment Systems.

OK, I thought you were talking about ozone generators.

Re: Question about \"DuctwoRx\"

Mike my guess is that you may be a whole lot more informed about helicopters than Honeywell Electronic Air Cleaners. All electronic are cleaners are not created equal.

Honeywell Air Cleaners are 20 to 40 times better at cleaning the air than typical furnace filters.

A standard one-inch disposable furnace filter is designed to trap only the larger, less troublesome particles, such as lint and large dust.

A Honeywell Electronic Air Cleaner is designed to remove up to 95 % of the particles in the air-including aggravating pollen, dirt, dust, grease, tobacco and cooking smoke and microorganisms. That's 20 to 40 times higher efficiency than throwaway furnace filters, making the Honeywell Electronic Air Cleaner the best air quality control product for your home.

Heating and cooling equipment will operate at peak like new, performance, because Honeywell Electronic Air Cleaners prevent dirty air particles from accumulating on the indoor coil and fan blades. Clean coils save 10 to 15 % in operating costs of the heating and cooling system

Do I sound like an old HVAC technician? I am. /forums/images/graemlins/grin.gif

However I have never heard of a electronstatic filer as you mentioned is that a variation on the electrostatic filter? /forums/images/graemlins/frown.gif

Re: Question about \"DuctwoRx\"

I never stated all filters we created equal. I do not have a typical furnace filter, never stated I did. I have an electrostatic filter as I noted above. If I spelled wrong, I am deeply sorry.

20 to 40 times? That is a huge percent here. Also compared to what?

Also so far Honeywell does nothing that a spaceguard (aprilaire), for example does not do.

The honeywell ones not kill bateria, paracities etc. My cheaper electrostatic one before my ductrx, effectively removes particulate from the air, such as allergens (including mold and dust mites), fine dust particles, bacteria, viruses, chemical fumes and other ultra-fine particles. Does Honeywell, nope.

Also you stated the “up to 95%” . Ok at what efficiency and what size? 10 micron, 5 etc. Big difference here. Honeywell the best? That is personal opinion and we know what that means. Also Honeywell Fseries filters (best they have) are over $500 and does not kill mold! What a deal. You could buy a Aprilair for $400 less and is 99% efficient at removing particles 1/100th the thickness of a human hair (1 micron) on a single pass. Add in the Ductrx and these two are better and cheaper.

I have a electrostatic that Traps up to a whopping 99.97% of particles & are very effective in trapping pollen, mold, bacteria, dust, pet dander and many other airborne contaminants, they can potentially reduce or eliminate allergy and asthma symptoms

Lastly, I am glad you are an old HVAC person. I am not an expect on anything. I am still learning new things daily. Just people someone does something a long time, does not mean they know everything. Any old dog can learn new things.
