Mine are significantly slower than the manufacturer's listed filtration rate. Am I the odd one out?

Couple of tips: Rinse off new filters, and season them by running clean water through them the first time you use them. Clean the surface of the filters with a soft scrub brush. As someone else pointed out, make sure the dirty water bucket with the filters is NOT air-tight or you will create a flow-stopping vacuum. Keep it filled with dirty water to help provide the water weight needed for optimum flow. Keep dirty water in it at all times. and transfer filtered water from lower catchment reservoir into water pitchers often to prevent overflow. If none of that helps. add filters. Drill the holes and attach new filters as necessary to increase filter system throughput.

We have used these in a home made water filter in Madagascar and here in the states. It is our experience that the more things your filter is cleaning out of your water the slower it is. However they did make river water in Madagascar drinkable.

We added filters for fluoride which could change the speed some. Our first set of filters worked pretty close to the manufacturers estimate, it seemed. We just changed the filters in January and they seem significantly slower, perhaps by 50%.

Hello, we had the same problem with 5 gallon buckets that we used with the filters. My husband drilled two very small holes in the very top of the bottom bucket to allow air in and it speeded up the filtration rate significantly. Hope this helps.

I just bought one to replace my original permanent filter which was somewhat smaller. I've noticed that water flows through faster with the new filter, and the brewed coffee is weaker. Adding a paper filter has helped.

It is slower than other, plastic filters I've had. After a few uses is seems to hit a rate of filling up in an hour or two. But then after a few more months, it started slowing down significantly. I took out the filters and gently scrubbed them with a soft brush as per instructions, put them back in and now it is back to normal. The more filters you have, the faster it will go. Mine came with two but had the capacity for four so I ordered and added the extra two. I tend to fill mine up before going to bed at night. Works great!

Runs very slowly so you know your going to have to change filter sooner better than later. Thats the way my unit worked.

Not a problem with mine. It could be a clogged filter or to much pressure/flow from the supply. Replace the element and/or turn down the flow rate.

I see that mine also takes a while to drain into the bottom tank. It did say it will go faster as it gets older and I suppose because of all the levels it has to filter through is why it is slow. I have noticed it takes over night to drain well. I try to add at night before bed and in the morning when ill be at work.

Just because you still have a good flow rate does not translate into you don't have to change the filters. It is important to chane them per mfg recommend times as the charcoal looses its ability to do its job with time and use and mold and fungus can be present (not a good thing) Poney up and change them.

One more thing on the higher filtration filters. As other comments DEPENDING upon your furnace/AC, they MAY BE took thick for adequate air flow. My installer/yearly check up company said ONLY use LOWER filtration for times when the Air Conditioner is used as they CAN cause freeze up. On the high efficiency newer furnaces, they can do fine with higher FPR rating. So I use 4 thinner rating in the summer and the 7 in the winter.

The 2 that I have purchased work just fine.. Don't think there's a slow flow insert in them..

You might want to check the pump for any kind of blockage,it does not come rushing our with any kind of pressure.I thought there would be more pressure coming out after I installed mine as compared to other filters I have had in the past...that is not the case with this filter/pump set up.

I don't have the extremely slow filtering issue. It doesn't seem normal to me.

Check both filters. Maybe they are dirty. Might be a partial clog inside System somewhere. Check for partial clog where the bag is connected.

Check to see if your water level is covering the entire intake pipe. It should be. Also, If you have the skimmer attachment installed, it might be contributing to the problem. I run my filter with it out of the intake line, with better results.

I think because your filter is impeded. Try removing the filter and clean off the debris.

Yes, the water flow rate of this system is very slow. There is nothing that I am able to do about it. The reason may be due to the fact that the water travels through 3 filters, the tubing used for the system are of narrow diameter and the water pressure in the house may be low. I use the filtered water only for drinking. There are only two people in our home and the quality of the filtered drinking water makes up for the slow water rate.

My water flow is excellent! A my previous filter aged, the water flow became considerably weaker.

I'm not sure so I would contact the manufacturers of the system and the filters. If it does not I am sure they would have an experts answer to your problem.
