Water filters

Post by Frothy » Tue Nov 07, 2006 9:07 pm

I'm looking at a water filter system but I'm not sure what I can get away with. I really want ~5micron filtration because this removes most microbes and particuarly protozoan cysts which survive chlorine treatment. Would this kind of filtration work with mains pressure water? Would I really need a pump to suck the water through at a decent rate?

what do you guys use?

Hi Matt, I just got one of these for filtering beer I'll find the details for you.

I also have a 1 micron filter fitted in-line to my cold water tap downstairs.

You need to check flow rates as some are awfully slow.

I bought my tap filter from machine mart and it was expensive compared to the one I've just got, especially as it's the same ruddy thing!

Give me a mo. :wink:

Right, the company is called H2Onics

www.h2onics.co.uk

My filter.

Filter housing AC100SCA 1/4" Ports, clear body 10", £19.88
ACB13 Bracket (for mounting filter) £ 4.35
AC25/1 1 micron wound polypropylene filter cartridge, £2.74
AC25/1 1 micron spun polypropylene filter cartridge £3.03
P+P 9.50

Gross total for my order was £51.53

These are some of the cheapest re-fills around and I looked a lot :shock:

No pump required!

I just use a POU carbon filter cartridge from B&Q which has John Guest posts on each end - fitted a JG tap connector to the inlet end with a hozelock connector fitted to the JG connector. So I can connect my water hose to it - for outlet I just fit some PVC tubing over the JG post.

Filter cost £9.99
JG tap connector £3 ish
Hozelock connector £2 ish

Make sure you get the right one Bigster! My local B&Q had lots of them recently (after a period where they had none)

£9.95 I believe.

I looked at similar ones to yours Andy (water gem amongst others) but the flow rate on most was 3ltr per min which was too slow for me.

30 seconds to fill my kettle....not likely, 10 min to fill my boiler...wasn't gonna happen :!:

Not according to the 'I'm Alan Partridge' I've just watched on UK tv gold.....Dan....dan :D

Timeless, and then you try explaining how funny it is to your sister and they tell you that they have just seen the funniest programme on TV....the Young Ones :roll:
There is an optimum flow rate for GAC filters, regardless of filter manufacturer. Too fast and they wont filter out chlorine and chloramine effectively.
Who's using a GAC?

I'm not advocating anyones filters but when I bought the one I did I was looking at long term cost.

The filter I bought lasts for 10,000 litres....maybe....total cost £51.

The one you've listed Andy, lasts 2500 litres and costs £10, so theoretically mid way into my second filter I'm cheaper than you....so to speak.

Reason being is that I filter all my drinking and cooking water so the offset cost for me is a LOT cheaper but horses for courses.

All this depends on variable factors, which, are not in our control.

I live in a heavily chlorinated area so the filters I've bought will not last as long as they're supposed too :cry:

Hi DaaB,

My Machine Mart filter for my tap supply is 'AC6X', a chloramines/organics filter

It is a 1 micron wound polypropylene filter produced by a company in Liverpool for a substantially higher cost.

They quoted a chlorine/chloramine filtration rate of better than 99.8%

If you ring MM's technical helpline (like I did) for technical help, they will refer you to this company for technical details as to the filters capacity and efficiency (though they will be quite aloof when they realise you know what your talking about) :!:

Ps, forgot to mention in the preceeding post how iratating it was to phone several 'respectable' water filtration companies who had no 'credible/independent' evidence to support their filtration claims.

Also, many of those that did use credible indepentent testing companies, were all to eager to say that there were too many variables, in any location, to validate the filters performance....in any location :roll:
