User questions & answers

Question:	Is this heavier than vloth masks due to tge 2 plastic valves
Answer:	Approximately 3/6" or 4.5mm.
Question:	Are these 100% cotton? And do they have a nose wire
Answer:	The water comes out as soon as you turn your hose on. No open or close.
Question:	Heavier than cloth masks due to the 2 valves
Answer:	It is the same as most single use high pressure nozzles. It is better than the adjustable nozzles. It will only get your deck really clean if you prep it with cleaner. It will leave ingrained dirt if you just spray with wather. FYI: The quality of the product is perfect.
Question:	How often should the filters be changed
Answer:	I was not satisfied with the force of the jet. I wanted to use it to clean my sidewalk and I found it lacking in power. So I would have to say it would not be enough for a 4" sewer line pipe.

Product description

The 3M Aqua-Pure Whole House Scale Inhibition Inline Water System AP430SS is designed to help reduce scale build-up and corrosion - thereby helping to extend the life on hot water-using appliances such as water heaters (standard (gas or electric) and tank-less), boilers, clothes washers and dishwashing machines, and on plumbing fixtures like faucets, pipes, and shower heads. The AP430SS provides a flow of up to 10 GPM with ¾” NPT inlet/outlet connections. Scale is calcium and magnesium deposits that often form when hard water is heated. Water hardness is responsible for most scale formation in pipes, water heaters, finishes and flat surfaces, and other water using appliances. Over time scale build-up can significantly shorten the life of any water-using appliance. Also scale buildup inside pipes causes loss of water pressure as the interior gets smaller and smaller over time. The AP430SS contains polyphosphates to bind calcium and magnesium hardness minerals, helping to prevent them from precipitating out (or becoming a solid) and building up on metallic surfaces. Polyphosphates also helps prevent corrosion by forming a thin protective layer on the metal surface. The 3M Scale Inhibition Water System AP430SS is tested by NSF International to NSF/ANSI Std. 42 for material and structural requirements only. The overall single vessel/cartridge design of the AP430SS makes the 3M Aqua-Pure AP431 Water Filter Cartridge change-out easy for professionals as well as end users. Change disposable filter cartridge every 6 months or sooner if you observe noticeable reduction in water flow rate. The AP430SS is to be installed on the cold water supply line of the water heater or at point-of-entry of water into the home. Tools and parts required (not included): one ¾” stop and waste valve (compression type), PTFE tape, two ¾” male x ¾” street adapters, one ¾” compression gate valve, and pipe cutter. Read all instructions carefully before attempting to start installation. The existing shut-off valve remains in place and still acts as the cold water shut-off. This filter system has 3/4” connections. The AP430SS can be adapted to various pipe sizes by using reducing adapter on either end. Installation fittings can be sweated or threaded. Use galvanized fittings for installation of galvanized pipe. Aquapure by Cuno hot water system protector to reduce scale build up in pipes and extend life of water heater. Installs on cold water side of hot water system to inhibit scaling and corrosion.

User questions & answers

Question:	Just received. It appears a lot of water bypasses the filter, can someone confirm this is not the case? Mine is just like customer uploaded photo
Answer:	Not a filter, a water treatment cartridge. Rated at 10gpm by the manufacture, a small amount of the water flow is diverted down into the cartridge through a single hole in the elevated tab, in the center of the tee. The polyphosate is slowly dissolved and a small amount of treated water flows back up and out 3 small holes around the elevated tab. According to the manufacture it only takes 2-3 parts per million to treat for scale. A little bit will do ya.
Question:	Does this help with water spots on glasses and scaling on bathroom fixtures
Answer:	We have a lot of calcium in our well water. The heat from the hot water tank is what causes the minerals to form scale. We placed this on the cold water side of the hot water tank and noticed a big improvement in water quality, especially on shower doors and dish washer. I have changed it twice now. The first time at 3 mos because the info says it can clean up existing scale in pipes and fixtures. The bottom line is if your water is very hard that will affect how much benefit you get from this product. So will you be happy with a 50% improvement in quality? I know I am cleaning faucet screens a lot less. Still have a jug of vinegar around though! Hope this helps.
Question:	GPM seems to low. I have 2 Tankless units, EACH one does 9 GPM
Answer:	we have an electric tank less that is rated at 4.5 GPM. We have very hard water in this part of MA and also have a well. We have been in this house for 30 years and have had problems with pipes rotting away. When we installed the electric tank less we installed this filter also. We used the heater for a few months and than had the plumber perform the maintenance suggested by the tank less mfg. It was clean as a whistle. Our flow rate is not as high as yours but if you had one in line with each heater - i would think it would work fine. Our heater used 120A for 4.5 GPM - if yours is electric it most use a lot of power! For our use I am very satisfied with the filter and given our water quality situation and how clean the heater was - i would highly recommend this filter.KR in MA
Question:	Can this system be installed with the filter in the horizontal position (copper pipe is running vertically
Answer:	In my opinion, if this is collecting any particles before getting into Tankless water heater, the particle should fall in vertical direction so filter should be installed in vertical direction. I installed my filter in vertical direction before cold water is getting in to the tankless. In order to get a right answer, it would be the manufacture because they are the one who designs the filter.

User questions & answers

Question:	When it will be available
Answer:	Depending on how often you use them and what you are using them for. If general everyday use for covid at least weekly or whatever is best for you. I purchased for construction work so I replace more frequently.
Question:	the mask have high quality

Question:	Does this mask work just as good as a N
Answer:	They are pretty much universal fit for all mask that have two breathing valves.
Question:	Where can I get replacement filters
Answer:	No they don't but they are directional in that you can aim the exhaust some what. Mine are pointed down and back towards my shoulders. Excellent question though, considering germs could escape out via exhaust but then some the masks I've seen aren't much better. They do provide the user excellent protection from germs, dust, and allergens if that helps.

User questions & answers

Question:	How often should the valves be replaced
Answer:	😷
Question:	Are the mask washable
Answer:	Yes... This is the prefect mask as it fits anyone due to the adjustable Velcro strap and ear loops. The filters work well too. I have found this to be one the highest quality masks available today.
Question:	Do these filter the air you breath out? In other words, you won't be breathing out the Covid-19 virus when you exhale
Answer:	No. From CDC "PM 2.5 mask (cloth pocket with replaceable activated carbon filter inserts) may work at some level, but we don’t recommended it because of insufficient data." Even a surgical mask is better. But sponge masks are worse. PM 2.5 particles are a sophisticated combination of different pollutants. The highly tiny particles can be lodged easily into your body. While PM 2.5 masks can be effective at preventing other things such as mist, and smoke, they are not ideal for protection against COVID-19. Coronavirus (SARS-CoV-2) is much smaller than PM2.5. The virus responsible for COVID-19 is roughly 125 nanometers or 0.125 microns in diameter. PM2.5 is 2.5 micrometers. Filtration efficiency of home-made cloth masks (~69.4%), surgical masks (~80%), and N95 respirators (~95%). Google "Beneficial cardiovascular effects of reducing exposure to particulate air pollution with a simple facemask" and "Testing the Efficacy of Homemade Masks: Would They Protect in an Influenza Pandemic?" for further reading of the studies. They'll be on nih.gov. I'm a MD/PhD Research Geneticist. Don't believe people that have no idea what they're talking about.

Answer:	The mask is made with the the outside mask material then there is a white material that lays toward your face. The filter goes easily between the two pieces of material. The filter is very light and easily inserted. I would suggest using the filter. You don’t know it’s there and when I’ve removed the filters, from the mask to wash, it has come out tannish. Went in white and came out tannish. So the filters do work. They are really nice.

Question:	What is the clamp for? my old one doesn't have a clamp and there is no explanation re the clamp in the instructions
Answer:	When I changed mine they lined up to the filter properly and same for the fronts, just make sure you plumb enough on the two front ports that you can cut away and re-glue things as necessary; think somebody posted this in the reviews and I almost forgot when I did mine. The bottom drain I never glued, just jam in the elbow when I backwash.

User questions & answers

Question:	Can i use this for a filter on my gas tank on my predator 212 and on valve cover breather too
Answer:	Yes, if it's the PM2.5, that's 2.5 micro particles, tested to filter 95 to 99% of the PM 2.5 rating. Check out the air quality ratings 2.5 is excellent.
Question:	is that For nitro rc car or use for vehicle
Answer:	Hello Veronica, yes you can wear glasses. We wear glasses as well. Occasionally they may partially fog up for a second or so if they are crooked on your face, but I pinch the nose guard and they work fine. I have purchased over 6 packs of these as a result of how well they wear. We even bowl with the masks and glasses on. Another thing: if it fits too close to your ears, you can remove the adjustment tabs to allow a bit more flexibility on the ears which allows a bit more space for breathing and not fogging up. Keep the tabs in a safe place in case you need to put them back on the masks. Hope this helps.
Question:	Can this go to any car
