Hi Darren that's a really good price have you used them ? Do they last ?

[mac74]

Has anyone got any actual REAL feedback on how good these cheaper HF4  vyair ones are? For a PROPER comparison?
I.E  Pure flow rate & TDS out .  AFTER they have previously used say a axeon, hydranautics, spectrum, or LG ect.  Ive just had a look on the vyair website and they are made by a company called Toray, which appears to be a decent brand, and they do sound good? They work out to be about £201 inc del, (the del is £25!  ) I have been paying around £265 inc del. from GAPS, for hydranautics hf4's which do give good results, (when new, 10 tds out  from 420 in, pumped @ 80psi, makes around 200l per hour) and the axeon's i used b4 that, were fairly similar. Im looking to buy another RO, but i dont know if its worth the £65 saving if the performance on the cheaper one doesn't stack up.
It would be good if someone has done the above, so we can compare them?
Cheers M

Hi, I've just bought a new 4040 from vyair as my readings were creeping on my old one to 37tds from 420, but its lasted 10 years some how. I see and hear people say they dont long life on there new membranes, are the quality of membranes poor and why is it they last 1 to 3 years on average. Whats the life span on these toray 4040 from vyair like? Thanks rob
