Product review (5 stars): Inexpensive protection for critical distillation equipment
I have a DolFyn water distillation unit. [Model A30D] City tap water entering the water intake valve must be super clean or the electric intake valve will fail and it is very expensive to replace. In addition, unfiltered water entering the boiling chamber means that you have to clean it more often which is a hassle and not inexpensive either. This 5 micron filter by Omnipure filters sediment effectively. I have used my previous one for 2 years before replacing it. I cut the old filter in half to examine the filter material and found that it was uniformy filled with debris from the tap water. [Your tap water source may require more frequent changes] This filter is expremely easy to change. Just push the 1/4" tubing into the filter end and it is water-tight. Just make sure that you cut a bit off the supply and  exit tubing each time so that the tubing is smooth where it goes into the filter ends. Also make sure that direction of the water flow is the same as the flow arrow printed on the filter. This filter is a must for anyone owning a distillation unit to avoid costly maintenance. Price was roughly half of what it is at retail locally. Delivery was one day late but considering it was during the Christmas and New Years holiday that is not unreasonable. Very satisfied with this filter and seller.
