Question: If I do not use my Berkey for a week, do I need to do anything special? Dump the water out and refill? Will the filters on the top dry out?
Document: So it makes good sense. Stainless can be sanatized, I like that about this unit. I would never use anything plastic to filet or store my water. It leeches poison in to your water so why filter it anyways, right? This is a pretty good initial expense so I researched water filters carefully. I chose this one because its stainless, can filter lake water if need be, is attractive on my counter, unlike others, and can be carried camping.
You need to use all four filters to get any volume out of this, but the filters can be cleaned and last a very long time, so get all four and use all four. So far I have filtered about 200 gallons with no problems.
We use this Big Berkey to filter our tap water, but I like the fact that I could scoop up creek water and come out with clean water after it goes through these four ceramic filters. The end result is good tasting water. We have a large glass dispenser with a spigot that we transfer the Berkey water to...that way we can always have a full container in process.
My Big Berkey is by far the best purchase of the season! Took a couple of days for the "ceramic" taste from the ceramic filters to disipate (can be avoided by rinsing the filters thoroughly and wiping with a clean dry lint-free cloth before installing them) but didn't want to add any contamination by too much handling. My son is the one who told me about the Big Berkey because I have been spending a fortune on bottled water for years.
4.5/5Great price for such a product. I love my new berkey filter and the clean water it supplies my family with. It did however arrive with two miner dents in the bottom piece and another dent in the top. Also the rubber stopper holding the spigot in place leaks when the knob is turned. It's not that big a deal and definitely worth the price.
Looks nice and the water tastes good. I only use 2 of the 4 filters and it makes plenty of water each day for my husband and myself. I bought a spigot with the site glass after reading other reviews. The spigot that comes with it is cheap plastic. Weird that they would make a nice item and put such a cheap spigot on it. I like that this requires no electricity.
I am on well water and have been buying bottled water for 12 years. No more plastic!!! After reading all the other reviews I also purchased the glass Spigot so you know how much water is in the lower chamber. A good idea. After running water through the filters 3 or 4 times the process really speeds up and the water is clear as a bell! I will use this item for the rest of my life!
IMO this is one of the best products on the market and the ceramic filters will last all most forever because of the way you can clean them. So if you need clean water without electricity this is the way to go.
This filter was everything I hoped it would be. I bought it a long time ago and waited a long time before posting a review. For the cost, I wanted to be sure. I use mine daily. It sits on my counter and I fill it with my tea pitcher. I use it for my coffee and drinking water. It saves my Pur faucet filter which the Pur only filters 100 gallons and each filter is about $10.00.
Been using this for about four months now. At first it was extremely slow, found out that the filters need to be totally saturated in water for a long time before it will really kick in and get the water through the filters. Something about air displacement. Totally filters smells, clorine, and gives some sweet water out. Will pay for itself in water bottles in the first couple of months.
Answer: yes
