Filter weight

Weight is another issue to consider. They are light when out of the box. After installing the filter & adding water, weight is gained. Moreover, adding some utilities to that will increase further more weight. This extra weight may bend or break the pipe & cause it to differ from the water fitting.

Material of construction

Many of them are made of plastic that lasts long &won’t corrode. Get plastic with finishes to match with other fixtures in the bathroom. Using bronze is limited.

Purification capacity

Manufacturers are aware about what their filters can do and that is not total purification. They don’t over-promise. Learn what contaminants these appliances target. They should eliminate: mercury, cadmium, arsenic, cobalt, zinc, iron, nickel, chromium, selenium, Bacteria and parasites.

Longevity of the package

Actually, they are not expensive. It will bother you if you need to buy them often after some default. Think of a filter that has an affordable & long-lasting cartridge that is easy to find.

Maintenance overall

For adjustable shower heads containing media & aroma filters in the handle, make sure to find one that is easy to maintain. It’s required to replace filters on these frequently. It should be a simple process. Couple of them have pellets in their handles.
