Air purifier

[CEAS-AC-TECH]

Guys. The wife is getting out of the hospital today after recovering from respiratory issues. My question is

Is getting an air purifier worth the $$$? I haven't done resi much since they came out and the cost are up there. I was thinking id be in for a couple hundred but looks like thats out the door.

Any leads to some that are affordable, fell off a truck lol and are worth the money are appreciated. Thanks

Usually I'd be cracking jokes, but my wife just beat death and is going to be on her way home. This thread in its entirety is of a serious nature. Minus the fell off a truck joke.
I really want to make breathing at home easy for her. Hence me asking about an air purifier.

Sorry.
I'm really glad to hear that she is doing a little better.
From all my reading on here I would really think the best you could do is decent filtration and control the humidity. I've never read anything that convinced me that ionizers and air purifiers and all those other things have any positive benefits and some of them have pretty definite negative effects.

No prob bro. No feelings hurt here. I figured I'd ask as i hear the same. I just haven't had the time to go back and read all over. In the past I've heard of negative effects but I forgot what they were. (Getting old) i reckon I can get better filters and keep the humidity relatively in a half decent range. I have a 4in honeywell filter base so I'll pickup some better filters and roll with that.

The main negative effects I know of is ozone but also ionizers can break down some compounds into more toxic compounds.

Consider UVC lights in equipment/ductwork.

I get that everyone has jumped on this as of late, but there is some real research to back up the claims made by some manufacturers.

It is my go to recommendation for clients looking for every advantage in reducing air contamination. Note, this is for commercial installations. But would happily spend my own money on a decent residential system if in your position.

Are you thinking stand alone room units, like the combination HEPA and/or UVs or in ductwork? Have installed some bypass HEPA filters on ductwork... But for me, I'd go with UVC as a first option.

Glad to hear wife is on the mend!

(Note, I have NO financial incentive for promoting such a product, beyond making a buck installing it.)

Hey thanks dude! I am looking into any and everything possible. So what ever I can fit into the plenum and or duct. Also a stand alone unit for the house. Any manufactures you would suggest looking into? Much appreciated.

Ok so I understand no ozone. I see a few that state no ozone and now im wondering how many lights? Like what one in the plenum, under the A coil, in the return? The system is 2y years old as in the house, so the duct is still clean and I have been changing the filter(20×25×2) every 2-3 months. There is a fresh air unit in the attic. The unit pumps air into the common space above the closet the AHU resides in. I just put a media filter on that one to help with filtration.

Im kinda liking the benefits the UVC lights have. So I'm looking at ones to fit in the unit or duct

Made a purchase I will be getting back with you guys on this once they come in it is a really affordable alternative to the high-priced solutions that we have to our accessibility. It is uvc lighting

Have you considered ripping out any carpet you have and replacing with hard flooring?

HRV system to ensure a good air exchange

Robot vacuum to help keep the dust off the floors?

My guess is any of those three would do better than a filtration system.

[CEAS-AC-TECH]

Yep the carpet will get ripped out soon as the funds allow. We have a hepa vac and keep it going daily. The pic is what I have for fresh air and will get a light setup as well. Much appreciated dude.

She went to the hospital and was faiding away. Only breathing out one lung. She's back home and near 100% still working on the respiratory therapy. I'm blessed as is she.

Sanuvox is what I've mostly installed on small furnaces or WSHPs. Brand choice more to do with local availability and support, than anything else.

Have read alot on UVC. Infact currently involved with a research study, for different high-end manufacturer, of its use in commercial business buildings and a reduction of employee sick days. Long term study with air/surface quality testing and data analysis by others, I'm just the installer and maintainer of equipment.

Cheers.

Good deal. I'd be interested to hear how that turns out once the study is complete. Sorta like a stay tuned at this point I guess. Much appreciated man.

The (2) lights I got are 120vac and said to omit zero ozone. They are setup like a flood light for out doors. I'll put one under the return and top the plenum shining down on the A coil. Then wire a low amp draw relay of sorts to the G terminal and set the stat to call for fan in heating and cooling for the on signal. Kinda pumped to see if and how this turns the air quality around.

UV lights don't really do anything to the air stream. Air flowing by them isn't in "contact" long enough to do a lot.

They are more affective keeping things from growing on surfaces.

I think you would be better off getting GOOD filters for your fresh air unit, and your furnace. If you really want something good, get some commercial grade HEPA box filters. They are EXPENSIVE, but better than standard pleated. You might also have to do a side stream system, due to pressure drop.

Teddy bear preaches fresh are changes and humidity control for the best indoor air quality.

There's also a system out there now that was developed for casinos. It doesn't generate ozone, but claims to clean by having what ever it generates combine with airborne contaminates. Forget what it's called...

You are on the right track. Start by providing fresh filtered, merv 13 when the home is occupied to purge any indoor pollutants and maintain high levels of oxygen. Keep the indoor air <50%RH and +40%RH. In your climate, you need a properly setup a/c, supplemental dehumidification during the humid seasons. During the dry months of you may also need humidification. American Medical Assn/ASHRAE suggest this a basic for indoor quality.

In most green grass climates, a small whole house dehumidifier with a fresh air option is a way maintaining <50%RH and the fresh filtered air change in 4-5 hours to keep the in indoor air quality as high as possible. Units the Ultra-Aire/Santa Fe made in Madison WI made for the application.

Keep us posted on what you do and how your wife does.

Mounting location and sizing of lights are important. Like you say contact time is paramount, as is intensity.

For the floodlight style, best to have mounted in a long straight length of return duct. With air stream flowing towards light.

Thanks for all the kind words and advice guys.
The lights are 72w each. From what I have found through research it seems this is the max or one of the highest wattages used. I will put one at the top of the plenum shining down on the coil and the other shining up at the filter in the return. I will have to fabricate a wall in the return to block off the light so it can not be seen through the vents. The lights should be here next week some time. The plenum install will be first as it will be the easiest of the two.

P.s.- don't mind the tape and crappy mastic. The installing contractor fingered the mastic on and i scraped it off to check the coil for leaks when the house was built. I still have yet to properly clean it up and redo.
