How does delivery work?

Free freight to the lower 48. Your order ships on a strapped pallet by insured LTL freight from the manufacturer's California warehouse.

When it ships. 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. Transit times are carrier estimates, not guarantees.

How you will know. You get a tracking number by email as soon as your order leaves the warehouse. Most carriers then call 24 to 48 hours ahead to lock in a four hour window, and some send an email or text the morning of delivery instead. Respond promptly either way, because missed attempts trigger terminal storage fees.

How it arrives. A 53 foot semi truck arrives at your curbside and the driver delivers the pallet to the curb. Liftgate service is not included as standard, and standard delivery does not include bringing the equipment inside, up stairs, or unpacking. Someone must be present to sign.

If it arrives damaged. Walk around the pallet and check every box before signing the Bill of Lading. Cosmetic damage can be accepted, but if a carton is punctured or crushed, refuse that item and call us on (888) 500-5675 while the driver is still there. Note the damage on the Bill of Lading, photograph it, and contact us within 48 hours. 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. Signing a clean Bill of Lading releases the carrier, and claims filed after one are routinely denied. If you refuse for a reason other than damage, or without contacting us first, return freight costs may become your responsibility.

Where it ships. Free freight covers standard residential curbside delivery within the contiguous 48 states. Hawaii, Alaska and Canada are not available at standard checkout, so contact us before ordering for a freight quote.

What does the warranty cover?

How long. Cold plunge tubs carry a 1-year limited warranty, when bought from an authorized dealer in undamaged original packaging.

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

Labor. Any labor cost associated with a claim is not covered. Coverage applies to the original purchaser and is not transferable.

What you have to do. Keep the water balanced and do not let it freeze. Corrosion from poor water maintenance and freeze damage are the two most common reasons a claim is declined. Keep your proof of purchase.

What is not covered. Fading or discoloration from UV exposure, damage from storage in below-freezing temperatures, and corrosion or discoloration caused by lack of water maintenance.

What if I need to return it?

30 days from delivery. The item must come back new, unused and in its original packaging with all components, hardware and accessories. Anything assembled, used or modified cannot be returned, and electronic components such as power supplies and control panels are non returnable under manufacturer policy regardless of condition.

What a return costs. The manufacturer may charge a 20 percent restocking fee, and you are responsible for the return freight. The original shipping cost is not deducted from your refund. Any storage or carrier routing fees incurred during the return are the buyer's responsibility.

Damaged on arrival. A different process, and you are fully protected. If you accepted the delivery and documented the damage on the Bill of Lading, we handle the freight claim and ship a replacement at no cost, with no restocking fee and no return shipping.

Cancelling before it ships. No fee as long as we have not yet submitted your order to the manufacturer. After we submit it but before it ships, an administrative fee of up to 5 percent may apply, and we waive it whenever we are not charged.

To start a return. Email your order number to sales@recoveryroomdirect.com and we issue a Return Merchandise Authorization number within one business day. Write it clearly on every box, because the warehouse will not accept returns without it. Refunds are issued within 5 business days of inspection.

Which brands. Applies to all Golden Designs Inc. brands: Dynamic Saunas, Maxxus Saunas and Dynamic Cold Therapy.

20-micron Micron Rating
4-Pack Cartridges Included
10" × 2.5" Filter Dimensions
0.8 & 1.0 HP Chiller Compatibility

Keep Your High-Performance Chiller Running Clean

DCT's 0.8 HP and 1.0 HP chillers are designed for larger water volumes — up to 135 and 150 gallons respectively — and they move water at a higher flow rate than the 0.6 HP unit. The 10" × 2.5" filter housing accommodates this higher flow, providing greater filtration surface area and a longer service interval before restriction builds up.

The mechanical cartridge captures dirt, silt, sand, and suspended particles at the 20-micron threshold — removing visible contaminants while maintaining the flow rate your chiller needs to operate. When the filter becomes loaded, flow rate drops, the pump strains, and chiller performance degrades. A fresh cartridge restores full flow instantly.

Key Features

20-Micron Particulate Filtration

Removes dirt, silt, sand, and suspended particles at 20 microns — the OEM-specified rating for DCT chiller systems.

4 Cartridges Per Pack

Enough for 2–4 months of regular use. Stocking ahead prevents lapses in filtration and unplanned reorder delays.

Quick Cartridge Swap

Standard 10" × 2.5" form factor. Slides out of the filter housing and replaces in under a minute with no tools.

Specifications

SKU DCT-Filter-10x2.5
Filter dimensions 10" × 2.5" (nominal)
Micron rating 20 microns
Pack quantity 4 cartridges
Filter type Particulate/sediment (mechanical)
Warranty N/A — consumable item

Compatibility — Important

These 10" × 2.5" filters are sized for DCT 0.8 HP and 1.0 HP chillers. The 0.6 HP chiller uses the smaller 5" × 2.5" filter housing.

✓ DCT 0.8 HP Chiller — All Editions ✓ DCT 1.0 HP Chiller — All Editions ✗ NOT for 0.6 HP Chiller

If you have a 0.6 HP chiller, you need the 5" × 2.5" filter (DCT-Filter-5x2.5) — available separately on our site.

When to Replace

  • Every 2–4 weeks for regular home use (3–5 sessions/week)
  • Every 1–2 weeks in high-use or commercial environments
  • When flow rate drops below 16 L/min — chiller may alert or sound louder than normal
  • When filter appears visibly discolored or clogged

Frequently Asked Questions

How do I know if my chiller uses this 10" filter or the 5" filter?

Check your chiller's HP rating. DCT 0.8 HP and 1.0 HP chillers use the 10" × 2.5" filter (this product). The 0.6 HP chiller uses the shorter 5" × 2.5" filter. If you're unsure, check your original order confirmation or the label on the chiller unit, or contact us at (888) 500-5675.

Why does this 4-pack cost slightly more than the 5" 4-pack?

The 10" cartridge is physically twice as long as the 5" cartridge and contains more filter media. The modest price difference reflects the additional material in each cartridge.

Does replacing the filter affect my water chemistry or sanitization?

The cartridge filter handles only particulate filtration — it does not alter water chemistry or sanitization. Your DCT chiller's ozonator manages microbial control separately. Replacing this filter simply restores flow rate and water clarity; it does not reset or affect the ozone system.

Can I use a third-party 10" × 2.5" filter instead?

While the 10" × 2.5" is a standard cartridge size used in many filtration systems, DCT recommends using their specified OEM filters to ensure the correct micron rating and flow characteristics for their chiller housing. Using non-OEM filters may affect warranty coverage. We stock only DCT-specified replacement cartridges.
