The OmniFilter OB5 Clear Whole House Water Filter Housing is designed for versatility so you can customize your filtration needs. The OB5 clear versatile filter housing does not include a filter cartridge, although it can accomodate any Omnifilter whole house cartridge.

This water filter housing installs anywhere in your home where filtration is needed and includes wrench and installation instructions.

The OB5 housing accepts the Omnifilter RS4, RS7 and RS14 filters. Omnifilter's OW40 wrench is used with the OB5 " Series A" housing, while the older " white head" model housings take the WC79-2P wrench.

The Product picture needs to be updated online. The product I received in the mail did not look like the one advertised. The one I received has a top with an intergrated bracket which is used to mount the unit to a wall. Because of the build in bracket the product should be sold with, left to right or right to left flow options.
