You rely on your Dolphin pool cleaner to keep the water sparkling, but even the best robot can’t do its job with a clogged or worn-out filter bag. Over time, debris builds up, fine particles slip through, and your cleaner loses suction. The solution is simple: replace the bag. Whether you have an older Dolphin model or a newer one, finding the right filter bag is essential for maintaining peak performance. In this guide, we review three top contenders to help you choose the best Dolphin pool cleaner filter bag for your needs.
Pros
- High-quality double stitching for durability.
- Broad compatibility with many Dolphin pool cleaners.
- Easy to install and remove for cleaning.
- Washable and reusable, offering long-term value.
- Effective 70-micron filtration for fine debris.
Cons
- May not fit non-Dolphin or older model variations not listed in compatibility.
- Requires regular rinsing to maintain optimal performance.
- No included installation guide beyond basic steps.
The Apopip 99954305-R1 Filter Bag is a 70-micron replacement designed primarily for Maytronic Dolphin Premier robotic pool cleaners, but it also fits a wide range of other Dolphin models. This bag is ideal for pool owners who want to maintain sparkling water without constantly buying new filters. Its heavy-duty cloth construction and double stitching promise longevity and reliable debris capture.
In real-world use, the 70-micron mesh traps fine particles like sand, dirt, and pollen while still allowing water to flow freely. The bag is washable, so you can simply rinse it out after each cleaning cycle and reuse it many times. This eco-friendly feature also saves you money over time compared to disposable alternatives. Installation is straightforward: just remove the old bag, slide the new one into place, and close the robot. Most users report a perfect fit on listed models.
The build quality is solid for the price point. The cloth feels sturdy yet flexible, and the seams are reinforced to prevent tearing under normal use. The white color is standard and blends into the pool environment. One minor drawback is that compatibility is limited to the models specified; owners of older or less common Dolphin units should double-check their cleaner's model number before purchasing.
There are no major cons, but the lack of a detailed instruction manual might be a slight inconvenience for first-time users. However, the process is intuitive enough for most people. The after-sales guarantee adds peace of mind, as the manufacturer promises to address any issues promptly.
Overall, the Apopip 99954305-R1 Filter Bag offers a great balance of performance, durability, and value. It is an excellent choice for Dolphin Premier owners looking for a reliable, reusable filter bag that keeps their pool clean without breaking the bank.
Pros
- High-efficiency microfiltration captures fine dirt, sand, and leaves for pristine pool water.
- Works with a wide range of popular Dolphin robot models, reducing the need for multiple filter types.
- Easy to clean and maintain with no special tools required.
- Affordable price compared to manufacturer replacement filters.
- Solid build quality with lightweight yet sturdy plastic construction.
Cons
- Not compatible with Dolphin Nautilus CC Pro or CC Supreme models, limiting its use for newer variants.
- Older versions of Active 10 or S50 may require removal of a plastic piece for proper fit, which could be inconvenient for some users.
- As an aftermarket part, it may not perfectly match OEM quality or warranty coverage.
The Ulticor Ultra Fine Filter Basket is an aftermarket replacement designed specifically for a wide array of Dolphin robotic pool cleaners. It is an ideal choice for pool owners who already own compatible models such as the Dolphin S50, S100, Active 10/15, Echo, T15, T25, Proteus DX3, Saturn, Cayman, Escape, and others. This basket is not intended for the Nautilus CC Pro or Supreme versions, so buyers should verify compatibility before purchasing.
What sets this filter apart is its microfiltration technology, which captures even the tiniest debris particles. In real-world use, this translates to a noticeably cleaner pool with clearer water, as fine dirt, sand, and pollen are effectively trapped. The basket is easy to rinse and clean every four to six weeks, maintaining peak performance without hassle. Users report that it fits snugly and works reliably cycle after cycle.
The design is straightforward: a white, lightweight plastic basket measuring roughly 9x5x7 inches. Build quality feels solid for an aftermarket part, though it may not have the exact finish of an OEM component. The inclusion of installation tips for older Active 10 or S50 units (which may need a small internal plastic piece removed) shows attention to compatibility details. A video guide is available upon request to assist with that adjustment.
Potential drawbacks are mostly centered on fitment limitations. Owners of Nautilus CC Pro or Supreme will need to look elsewhere. Also, the need to modify older robots could be a minor inconvenience for those not comfortable with simple DIY tasks. However, for the vast majority of compatible users, installation is plug-and-play.
Overall, the Ulticor Ultra Fine Filter Basket offers excellent value for money. It delivers superior filtration at a lower price than official replacements, while covering a wide range of popular Dolphin models. If you own one of the listed robots and want to keep your pool sparkling clean without breaking the bank, this filter is a smart buy.
Buying Guide
Compatibility with Your Dolphin Model
Not every filter bag fits every Dolphin cleaner. Before buying, check the manufacturer’s compatibility list. The Replacement for Dolphin Pool Cleaner Parts works with many Maytronics models, while the Dolphin Genuine Replacement Part, Filter Bag is specifically designed for older models like the Deluxe 5 and Discovery. The 99954305-R1 Filter Bag 70 Micron Replacement offers broad compatibility too. Always verify your model number to avoid a mismatch.
Filtration Efficiency (Micron Rating)
The micron rating determines how small a particle the bag can trap. A 70-micron bag captures dirt, sand, leaves, and most debris, but may let through ultra-fine particles. For crystal clear water, consider upgrading to a Dolphin fine filter or ultra-fine filter for even smaller microns. Both the Molidan and Apopip replacements offer 70-micron filtration, which is standard for most residential pools.
Durability and Build Quality
A filter bag needs to withstand repeated use and washing. Look for double-stitched seams and heavy-duty cloth. The Apopip bag is double-stitched and made from extra heavy-duty fabric, making it washable and reusable. The Dolphin genuine bag is certified for durability, while the Molidan bag offers solid construction at a lower cost. All three can be rinsed and reused multiple times.
Ease of Installation and Maintenance
Replacing a filter bag should be quick and hassle-free. Most bags attach with a simple clip or strap. The Apopip bag installs in four steps: remove the old bag, clip in the new one, and close the robot. All three bags are washable, but the Dolphin genuine bag is the easiest to clean due to its fine mesh design.

Final Thoughts
After reviewing the top options, we recommend the Replacement for Dolphin Pool Cleaner Parts for its high rating and solid performance, while the 99954305-R1 Filter Bag 70 Micron Replacement stands out for its excellent durability and broad compatibility. Both will keep your pool pristine without breaking the bank.

Frequently Asked Questions
How often should I replace my Dolphin pool cleaner filter bag?
It depends on your pool usage and debris load. As a general rule, replace the bag every 3 to 6 months, or when you notice reduced suction or visible tears. Wash the bag after each use to extend its life.
Can I use a 70-micron bag in any Dolphin model?
Most Dolphin pool cleaners accept 70-micron bags, but always check compatibility. Models like the Dolphin Premier, DX3, and DX4 work with the bags reviewed here. For older or specialty models, confirm with the manufacturer.
Is a higher or lower micron rating better?
Lower micron ratings (like 50 or 30) trap finer particles, producing clearer water but potentially clogging faster. A 70-micron bag balances filtration and flow rate, making it ideal for general pool maintenance. For ultra-fine filtration, consider upgrading to a Dolphin ultra-fine filter basket.
Can I wash and reuse a pool cleaner filter bag?
Yes, all three bags in this review are washable and reusable. Rinse them with a garden hose after each use to remove debris. For deeper cleaning, soak in mild soapy water and rinse thoroughly. Replace when the material shows wear.
