I purchased the replacement filter set so that I would be ready for when it is needed. The good thing about the filter set is that there are actually two sets inside and wherever I happen to be when they are needed for my ION330 purifier, which I use in our motorhome, it will be easy to replace them. I am very happy.
Easy to install, but a bit mistified as to why there were 5 filters when only 3 needed replacing. The unit is functioning well.
Yes my ordered product did arrive OK however I was disgusted to find that I had had to pay $15 postage for a package which weighed a mere 144gm. I understand that you probably have categories whereby a parcel weighing between so much and so much costs the minimum amount and the lighter parcels subsidise the heavier ones etc. However I have revceived much heavier parcels than this one for a postage charge of $4.99 and know that this amount would have more then covered the cost of postage for this parcel. $15 postage for this very light parcel was a total rip off. NOT HAPPY!!!!
