Vent Stack Filter is rated 4.3 out of 5 by 41.
Rated 3 out of 5 by from Installation info inaccurate I recently ordered 30 of your sweet air vent caps for a local school. In your literature and on the box you explain; solvent weld the fitting to 3" and 4" schedule 40 pipe. Your 3" size is actually a smaller diameter than 3" sch 40 PVC and there is not a pipe or coupling that will fit tight enough to solvent weld. After trying several different connectors I found that your 3" is actually copper tube size which is rare for drains these days. I had to use a Fernco clamp that went from 3" copper tube size to 3" sch 40 pipe these clamps were an unplanned added cost. . Please either restate what pipe you are able to connect to or change the connector size on your product to actually fit 3" PVC.

Rated 5 out of 5 by from A solution to the problem! We had a very heavy odor coming from our septic vent for years. I finally found this product which is working good so far. The odor seems to be gone, tho it is cold outside, the true test will be in warmer months. Product was fairly easy to install. I did think is was a bit overpriced, but other similar products I saw online were more expensive, so overall a good value. I would recommend this product.

Rated 1 out of 5 by from Made problem worse I bought this product because I could occasionally smell septic odors outside my house. Thinking it was caused by the vent stack vapors coming from the vent stacks on the roof I bought two filters for two vent stacks. The "universal" installation is not universal at all and I needed extra parts to install them on a 2 inch and 4 inch vent stack. Once installed I thought they were doing a terrifc job. I could no longer smell the odor while standing directly over the vent stacks. Turns out the filter actually completely blocked the vapors from going outside. Next thing I know my whole house stunk on the INSIDE. And yes, I did remove the plastic bag around the charcoal filter before installing. Save your money and do not use this product.

Rated 2 out of 5 by from Not worth it All it did was cause more back pressure, thus more odor inside. Less odor without it.

Rated 5 out of 5 by from Very satisfied with results. We have put up with septic smell from our roof vent for several years. I finally did a web search to find a solution. There are many products but felt the reviews for Sweet Air were positive and liked that it sold through Home Depot for easy pick up and return if necessary. From the day it was installed there has been NO smell. Why did we wait so long to filter the vent? I marked 4 stars on ease of installation only because we had to add a reducer to fit it to a 2 inch pipe. The part needed was gotten from H D. I added a 2 inch rubber coupler using band clamps to fit the whole assembly to the vent, in place of gluing it directly to the vent pipe. That allows easy removal if and when the filter is not needed .. as is true in the summer months. Again, totally satisfied with the results.

Rated 5 out of 5 by from THE ANSWER to your septic smell problems! REALLY! We moved into our home one year ago right after the previous owners installed a brand new septic tank. We noticed the horrible odor right away. We called the septic tank installer out and it was explained to us that the smell was because the tank was new and we needed to add Rid-X. We did. No change. Then it was explained to us that the smell was because our house was in a canyon and the septic gasses have no where to go. It was embarrassing explaining the smell to guests every time we had an outdoor party. My husband did A LOT of research and discovered Sweet Stacks. He easily added an adaptor fitting and installed three on the vents on our roof and instantly...PROBLEM GONE! We had a very large party outside the following weekend and I was thrilled...nothing but the fragrance of orange blossoms. SWEET! I highly recommend this product.

Rated 5 out of 5 by from Worked Perfectly. Two weeks ago, my new place stank. I was worried about having to dig up the septic system. The smell was tracked down to the roof vents. I installed these almost two weeks ago. No stink now. Relieved. Placed them on all the vents up there, bathroom vents were the worst offenders. Would buy again. No evidence of stink, verified by my wife's sensitive little nose.

Rated 5 out of 5 by from works as advertised This simple item works excellent at eliminating the odor from the septic system venting. The hardest part was getting out the ladder to get on the roof. Glad I got it.
