How to Choose

First decide how many filtration stages you want. The AR2 Essential Kit (BT-AR2-ESNBNDL) is a 2-stage system for sediment and chlorine reduction; the AR3 Essential Kit (BT-AR3-ESNBNDL) adds a third stage with a Granular Activated Carbon Coconut Shell 'TASTY' filter for even better taste. Both kits include a stainless quick-connect hose, pressure regulator, and 3-way splitter, so first-time buyers should start here rather than piecing parts together. Once you own a kit, buy the matching recharge pack: BT-2FRP for the AR2, BT-3FRP for the AR3. If you already have a system and just need accessories, add the BT-SPLTR3-SS splitter to run three hoses at once, the BT-RGLTRSS regulator to protect plumbing (0-160 PSI adjustable), or a stainless hose in 5 ft (BT-HSE-5-UNIV) for tight hookups or 25 ft (BT-HSE-UNIV-25) to reach distant spigots.

Frequently Asked Questions

What's the difference between the AR2 and AR3 kits?

The AR2 is a 2-stage system reducing sediment and chlorine. The AR3 adds a third stage with a Granular Activated Carbon Coconut Shell 'TASTY' filter for improved taste. Both include a stainless hose, pressure regulator, and 3-way splitter.

Which recharge pack fits my system?

Use the BT-2FRP 2-pack for the AR2 Essential system and the BT-3FRP 3-pack for the AR3 Essential kit. Filters install without special tools.

What comes with the Essential Starter Kits?

Both kits arrive with a stainless steel quick-connect hose, pressure regulator, 3-way splitter, and pre-installed filters, so they're ready to hook up out of the box.

Do the splitter and regulator work with both kits?

Yes. The BT-SPLTR3-SS splitter and BT-RGLTRSS regulator are compatible with both the AR2 and AR3 Essential RV Starter Kit systems and standard hose connections.
