Dynamic Cold Therapy 20 Micron Replacement Water Filters - 5" x 2.5" (4-Pack)

Your order ships free from the manufacturer's California warehouse on a strapped pallet via insured LTL freight. Orders are processed within 2 to 5 business days depending on the brand, and delivery to most addresses in the contiguous US takes 5 to 14 business days after shipment. See the brand section of our shipping policy for the times that apply to your product. You'll receive a tracking number by email as soon as your order leaves the warehouse.

Scheduling your delivery. The freight carrier will reach out before the truck rolls — most carriers call 24–48 hours ahead to lock in a four-hour delivery window. Some carriers (including R+L) send an email or text the morning of delivery instead. Respond promptly either way. If the carrier can't reach you and misses 2–3 delivery attempts, terminal storage fees kick in and the item may be returned at your expense.

What to expect at delivery. A 53-foot semi-truck arrives at your curbside. The driver uses the truck's built-in liftgate to lower the pallet to ground level — that's where their responsibility ends. Standard delivery does not include bringing the equipment inside, up stairs, or unpacking. Plan ahead: have help available to move it once it's off the truck. Someone must be present to sign for the delivery.

CRITICAL — inspect before you sign. Walk around the pallet and check every box before signing the Bill of Lading. Cosmetic damage can be accepted. If a carton is punctured or crushed, or the sauna itself is damaged, refuse that item and call us on (888) 500-5675 while the driver is still there. Note the damage on the Bill of Lading before you sign, writing exactly what you see, and ask the driver to initial it. If the driver will not initial it, note the damage anyway, sign, and photograph the Bill of Lading. Contact us within 48 hours with photos. Once the damage is documented on the Bill of Lading we can file a valid freight claim and ship a replacement at no cost to you. If you refuse for a reason other than damage, or without contacting us first, return freight costs may become your responsibility. Signing a clean BOL releases the freight carrier from all liability. Claims filed after a clean signature are routinely denied. This takes two minutes and fully protects you.

Good to know. If your address changes after the order ships, contact us immediately — carrier re-routing fees may apply and will add transit time. If your location cannot comfortably accommodate a 53-foot semi-truck (island, remote road, gated community, narrow access), contact us before ordering so we can arrange an appropriate solution.

Questions before you order? Call or text (888) 500-5675, Mon–Sat 9am–6pm EST. We coordinate every delivery ourselves.

Free freight applies to standard residential curbside delivery within the contiguous 48 US states. Hawaii, Alaska, and Canada are not available at standard checkout — contact us before ordering for a freight quote. Transit times are carrier estimates, not guarantees. Applies to all Golden Designs Inc. brands: Dynamic Saunas, Maxxus Saunas, and Dynamic Cold Therapy. View our full Shipping & Delivery policy →

Dynamic Cold Therapy cold plunge tubs are covered by a 1-year limited warranty from Dynamic Cold Therapy, on tubs purchased from an authorized dealer in undamaged original packaging.

What's covered. Defects in materials and workmanship: the polycarbonate insert, the wooden shell and trim, and all other components each carry 1 year. Chillers carry a 1-year manufacturer warranty. Insulated covers carry 1 year and neoprene hose covers 90 days; replacement filters are consumables with no warranty.

What's not covered. Fading or discoloration from UV exposure, damage from storage in below-freezing temperatures, corrosion or discoloration caused by lack of water maintenance, and any labor cost associated with a claim. Coverage applies to the original purchaser and is not transferable.

Keep the water balanced, and don't let it freeze. Corrosion from poor water maintenance and freeze damage are the two most common reasons a claim is declined. Ask us for the maintenance schedule — we'll send it with your order.

Keep your proof of purchase. Note that Golden Designs' 60-day registration portal covers infrared saunas only and does not apply to cold therapy products.

How to make a claim. Contact us — as your authorized dealer we handle the claim with the manufacturer for you. Email sales@recoveryroomdirect.com or call (888) 500-5675 with your order number and photos of the issue.

Summary of the manufacturer's warranty. Their official warranty document governs.

We stand behind every product we sell. If it's not the right fit, you have 30 days from delivery to return it — and if you need to cancel before it ships, there is no fee as long as we have not yet submitted your order to the manufacturer. After we submit it but before it ships, a 5% administrative fee may apply, and we waive it whenever we are not charged.

How to start a return. Email us your order number at sales@recoveryroomdirect.com and we'll issue a Return Merchandise Authorization (RMA) number within one business day. Write that number clearly on the outside of every box before handing it to the carrier — the warehouse will not accept returns without it.

Condition required. The item must come back new, unused, and in its original packaging with all components, hardware, and accessories included. Items that have been assembled, used, or modified cannot be returned. Electronic components — power supplies, control panels, and accessories — are non-returnable under manufacturer policy regardless of condition.

What it costs to return. We want to be upfront about this: returning large freight equipment has real costs. The manufacturer charges a 20% restocking fee on all returns, and you are responsible for the return freight. If your original order shipped free, the actual outbound freight cost is also deducted from your refund. Any storage or carrier routing fees incurred during the return process are the buyer's responsibility as well. Once the item arrives at the warehouse and passes inspection, your refund is issued within 5 business days to your original payment method.

Damaged on arrival? That's a different process entirely — and you're fully protected. If you accepted the delivery and documented the damage on the Bill of Lading, we handle the freight claim and ship you a replacement at no cost. No restocking fee, no return shipping. This is exactly why we ask you to inspect carefully before you sign.

The manufacturer warranty covers defects that arise after the 30-day return window. See full warranty terms at goldendesigninc.com. We're here Mon–Sat, 9am–6pm EST. Applies to all Golden Designs Inc. brands: Dynamic Saunas, Maxxus Saunas, and Dynamic Cold Therapy. View our full Return Policy →
