Caliza Home is a small American company in Southern California. We sell filters for the house: furnace, shower, and whole-house cartridges.
We only list brands with a real track record. Aerostar furnace filters are made in the USA in Florida. Sprite shower filters are made in Corona, California. Other cartridges in the shop are named brands we can actually buy, not mystery clones.
Buying here supports this company. We are not a giant marketplace. If a product cannot meet that bar, it does not go on the site.
We do not soften water, treat skin, or sell medical devices. Measure the old filter before you order.
