Undersink System Tank + ULTIMATE Series Replacement Filter

The APEC Water Systems Tank-4 4 Gallon Residential Pre-Pressurized Reverse Osmosis Water Storage Tank in White is designed to provide high-quality water storage for most residential reverse osmosis systems. These durable metal tanks deliver a continuous and stable supply of purified water at a fast flow rate, making them suitable for average to large-size families.

Supported by fully enclosed polypropylene and butyl reservoirs, these storage tanks offer airtight protection against leaks. Their stainless steel connectors ensure leach-free integrity, while post-cured diaphragms eliminate the possibility of odors from the tank. Each tank is individually pressure-tested for safety and certified for materials quality, safety, and durability, making them suitable for use worldwide.

The tank's dimensions are 11 inches in diameter and 15 inches in height, with a weight of 10 pounds. An optional tank ball valve with a 1/4-inch connection to 1/4-inch or 3/8-inch tube size is available (not included with the tank).

APEC Water Systems also offers the ULTIMATE Series Filter-Set, a high-capacity replacement filter set made in the USA. This filter set is designed to provide longer-lasting performance and high-quality impurity removal for your reverse osmosis system.

The filter set includes a 10-inch high-capacity polypropylene sediment filter in the first stage, which removes dirt, particles, and rust. The second and third stages feature premium extruded carbon block filters that effectively eliminate unpleasant chlorine, tastes, odors, cloudiness, and colors, as well as removing VOCs and other common harmful impurities.

APEC's extruded carbon block filters are superior to granular activated carbon (GAC) filters, as they do not channel or bypass due to the extreme uniformity of their extruded activated carbon core. These filters are compatible with APEC's RO-45, RO-90, RO-PERM, RO-PUMP, and all other standard-size under-counter reverse osmosis systems.

For over 17 years, APEC has been an industry-leading manufacturer specializing in high-performance reverse osmosis systems. The company's dedicated team is committed to providing customer satisfaction and ensuring years of enjoyment and good health for users and their families.
