"This appears to be a very high quality device----but the strainer mesh was finer than I expected (my mistake----I just didn't understand how fine 80 mesh would be) ----so I had to return it and exchange it, I had intended to use it on my ditch water irrigation line and the water there is so dirty that the 80 mesh would have been instantly plugged------. The design of the strainer and the large area of the filter is superior to anything else that I had seen before."

"It was what I ordered and showed up promptly."

"These are the best filters."

"I eventually gave up and removed it from the system and purchased another strainer on Amazon which has glue in socket fittings."

"Results: faucet tap= 328ppm. aquafina bottle water= 2ppm. kirkland (Sam's Club bottle water) = 20ppm. and the apec water = 25ppm."

"I was impressed upon opening it as the main filter housing unit seemed very high quality and heavy. You can push the lever down and hold it if you just need to fill a glass or you can flip it up until it locks and and it will continually dispense until you turn it off. Some of these faucets require a 1 1/2" hole, and that would concern me because I have a synthetic granite/composite sink that it tough as nails to drill into. TIP: Once you locate where you want the faucet mounted, get a thin piece of wood (such as a shim) and drill a 1/2" hole in it. In my case, it took me a good ten minutes to drill through my sink (probably a 1/4" thickness) and the bit was completely useless once I got through the surface. Once the hole is drilled to your liking, follow the illustration for assembling the hardware for the faucet and mount it. I have a 2200 square foot ranch that was built in the eighties with that nasty, defective polybutelene plumbing and, after a ruined master bath and another close call in the kitchen after owning the house for just 6 months, I had my plumber completely re-pipe to the tune of 5K. If you decide to do this, the only one you won't be able to use one on is the yellow line that goes from the RO unit to the tank (because it has a crimped-on special two-way valve). One word of caution though- if you do this be very careful and mindful that you are screwing a metal compression connector onto plastic threads on the unit. My advice, in hindsight, is to determine where you're going to want the unit and place it there prior to beginning the install. It took me longer than it probably would have taken most people, but I have a unique kitchen sink with funky plumbing (couldn't use 1/2" adapter included to feed system from faucet bottom, instead had to convert down to 3/8" and run from cold water valve)."

"We already had a separate "beverage faucet" (with simple inline carbon filter) mounted on our sink so it was pretty much plug and play. I'm using a Watts Premier 560087 as the 5th stage filter (last is the carbon filter) in our APEC ROES-50. Never had acid reflux before with our inline filtered water used to brew coffee. P.S - I know APEC makes a remineralizing/pH filter, but the Watts filter contains additional minerals such as magnesium and potassium, whereas the APEC filter is just calcium. It installs in between the tank and the tee, vs the 1-way "final filter" of the APEC (probably why it doesn't raise the pH that much - water passes through it too quickly). The tee just replaces the 1/4 x 1/4 x 1/4 existing tee on the RO system For the 3/8" final filter, I really like the Hydronix filters, I used B00D04BYIK (again, search on Amazon), but any 3/8 inline carbon filter will do."

"we have a pretty clean house so I usually don't see much dust on these filters but it's nice to know these pick up stuff so we don't wind up breathing it."

"The "big box" stores have filters but I have to dig through to find the sizes we need and they sometimes have low quantity."

"The price was right for multiple filters."

"To my dismay, I noticed that the new filter had several thin spots in it, not unlike the less expensive fiber filters I prefer not to use. Well, not only was the newer one noticeably thinner, there were 3 fewer pleats in the filter."

"Higher rated filters will only reduce the efficiency of your heating and A/C systems and end up costing you more for the filters and in utility costs. A tip I was taught to improve your filter's MPR rating without impacting air flow is to give the filter a quick spray with Pam (or similar) each time you replace the filter. As much as I want to switch brands entirely, I am giving 3M's 600 MPR filters a chance first (Filtrete Clean Living Dust Reduction Filters, 600 MPR, 20 x 25 x 1, 6-Pack). 3M claims they provide better filtration AND are more efficient at allowing air through then the 300 MPR filter, which makes very little sense, but, OK. At first glance they seem a lot like the 300 MPR filters used to be before the quality went downhill. UPDATE 4: It's January 2016 and I've made the switch to the comparable Nordic Pure product (Nordic Pure 16x25x1M8-6 MERV 8 Pleated AC Furnace Air Filter, 16x25x1, Box of 6)."

"Do not buy these, they are not safe."

"Spend the money for the High Performance version - it won't be a wast of money like these cheap quality filters - and your body and your ducting system will thank you."

"When the a/c unit ran and drew in air the filter bowed in excessively by the air flow."

Reviews

"I used it to drain the coolant from the reserve container on my vintage Honda CX500 motorcycle so I didnt have to remove the container since it was a tight space where it was located---so this definitely saved me so much time."

"Glad I went with smaller version there was some distortion of the plunger under very high draw (vacuum) that may have been worse with the larger model."

"I also purchased a few Turkey Basters here on Amazon that basically do the same thing for pulling old brake fluid or power steering fluid out of master cyclinders or pump reservoirs to replace with new fluid."

"No problems, used it to suck the old oil out of my supercharger and it worked like a champ."

"This makes accurate measuring a little tricky to calculate... basically, you'd want to stop at 90ml, then clear the hose into the syringe to get you to about 100ml."

"I doubt the elastomer plunger gasket would be resistant to oil based fluids so be sure to avoid contact with the plunger and any such fluids and clean thoroughly immediately if you plan to re-use the syringe."

"I was using this syringe with plastic tube to transfer home made hot sauce in exact amounts into containers for family and friends."

"The hose DOES come off the syringe, which actually worked out, as I could empty the syringe without pulling the hose up from the bottom of the transmission."
