Dust collector/filtration

[Paulski]

I'm getting ready to rip out about 25' of a tile counter top and back splash in the kitchen. Trying not to make a mess of the house, any recommendation on an air filter/collector unit to help keep dust from going everywhere? I plan to hang sheeting to confine it to the kitchen (plus wear PPE for me), there is a window that could be used to blow the duct out of.
I was thinking something like this

Or am i over engineering and a box fan in the window good enough!

I am getting to the end of a kitchen remodel. I hung plastic to isolate the rest of the house and closed off all the heating supplies for the area. I had a decent fan and run a duct to a window and sucked all the dust outside. The plastic wasn't tight, but with a fan it pulled air out of the rest of the house so dust didn't have a chance to travel that direction. Surprisingly, it worked well and the rest of the house is fairly clean. We also wore decent respirators rated for asbestos when we were doing the worst of it.

Personally, I wouldn't bother with the Grizzly filter, unless you have a use for it later.

I have two of those type filters. I wouldn’t bother with using that. We were excavating a large area under our house using a Bobcat with the exhaust filter so we wouldn’t pollute the air in the house above. After one day of that I bought a 200 dollar industrial high volume fan. Cut a hole in the wall and fired it up. Opened a hole about 3x3’ in the opposite side which allowed a huge amount of air to move thru. I would suggest that over the air filter solution.

yea box fan should be good. You can tape the doors with plastic but the fan will need air from someplace. Tile should pop off in chunks not a dusty thing. The substrate should also come in pieces no matter what the material. Are you thinking there is metal lathe and going to use a saw or something?

We've used the above w/ excellent results... they're pretty tough, survived Burning Man, construction dust, etc. Three speeds, and much less likely to fall over than a box fan.

The best way to control dust is to remove it at the source of where it's produced - thus, use power tools fitted with a collector system and hook it up to a shop vac or HEPA system.

The Grizzly is only intended to take out what is goes airborne afterward that was missed, and doesn't have a lot of draw. If you're sheeting the area off and exhausting out a window anyway, why bother to try to capture it? You can skip it and just use a fan.

I cannot envision what in a tile countertop removal would create enough dust to not be able to clean it up with a shop vac and a broom ?

If you're ducting out a window, you're going to need makeup air, and you're going to expel conditioned air. If that's all good with you, then yes, a fan in a window will help a lot. Otherwise, a scrubber can be used to clean the air without wasting conditioned air. You can buy the type in your link, or build a better one for way less. Here is one of the units I put together:

Hanging air filter discussion and recommendations

I already have some box fans with filters and they do a good job but especially when wire wheeling rust it seems to rise immediately so I've been looking into the hanging systems to supplement. My space is 28x28x13 so about 10k cubic feet. I can't decide if I should get a singler larger unit or...

I built one with a box fan and 4 filtres. For cheap and duct tape. They are all over YouTube

If you have a use for it after I would get it. I bought one after we ripped out our flooring because of all the dust. I had it running when the new flooring was installed and it captured a lot of dust. Also had it going in my daughter's room when we had new insulation installed despite the room being completely sealed off.

I keep mine hanging in my shop though and run it as needed. The Wen version of that air filter is only $129. That's what I've been using for the past few years.

the hanging ones like the Wen shown are great for the fine, lingering particulate but they will NOT get everything. My old woodshop can attest to that, even with capturing at the source + running the WEN for a couple hours after work was done.

it helped. I might stick it in the garage for grinder dust and stuff since I don't have a woodshop setup anymore. but it's not going to capture heavy demo dust.

box fan in the window has always done well for me, as long as you have source air to pull through. If you don't, it does nothing. made that mistake once, had the room sealed too tight

 

[racecougar]

Agreed. That WEN is only rated at 400 cfm on high, and the Grizzly is just 260 cfm! The unit I mentioned in post #8 moves 3X-4X as much air.

I used one of these on my grinder to cut tile:


It worked reasonably well, but noting is going to work 100%. I was still cleaning up dust for a few months after all over the house.

My best advice:
- Send your wife to the spa during the cutting. Give the folks there a tip to hold her with sufficient time so you can clean up and vacuum the drapes.
- Pay for a purpose-built grinder for tile cutting with a built-in water system. (no dust!)
- Go for a home-built solution like this for your one-time job to eliminate the dust: https://www.facebook.com/misha.winni/videos/amazing-tool-for-your-grinder/868034121380583/

Wait, are we cutting tile or just removing tile?

A fan in a window will work fine. Your hanging plastic will not be a perfect airtight seal so air source for the fan will be the rest of the house. You might want to crack a window in another room a few inches. I'd buy a $25 box fan. You will be surprised how much air it moves on high speed. They are usually 3 speed so you can adjust as needed.

I used your basic window fan forcing air OUT the window when we gutted our 12' x 18' family room back to the studs. There was fiberglass insulation in the ceiling and fiberglass and blown in cellulose insulation in the walls. It was quite a dusty mess. The fan did a great job keeping the dust from migrating to the rest of the house. Hosed the fan off afterwards and it was fine.



I'm glad we renovated the room back then as it's where I'm parked when I WFH 245 days per year.

Cheers
