Best Storage Case for NiSi Square Filters
Investing in high-end glass like NiSi square filters is a game-changer for landscape photography, but keeping those fragile 100mm plates safe in the field is a constant anxiety. Standard pouches are often too flimsy or lack space for the bulky filter holder. After years of fumbling with gear in sub-zero sunrises, I’ve found that the NiSi Caddy is the gold standard for protection. In this guide, I’ll break down the best storage solutions to keep your kit organized and scratch-free.

Best Storage Case for NiSi Square Filters: Detailed Reviews
NiSi Caddy 100mm Filter Pouch View on Amazon View on B&H
If you are already using the NiSi V6 or V7 holder system, the NiSi Caddy is a non-negotiable addition. It is specifically engineered to house up to nine 100x100mm or 100x150mm filters, while still leaving a dedicated slot for the V7 holder itself. I personally love the flip-top design; it stays open on its own, which is a godsend when you’re wearing gloves and trying to swap a graduated ND filter during a fleeting sunset. The build quality is a shock-resistant semi-hard shell that feels incredibly premium. It also features a tripod strap, allowing you to hang the case directly from your tripod leg for rapid access. While it is bulkier than a soft pouch, the peace of mind knowing your $200 glass plates won’t crush under pressure is worth every extra inch in your camera bag.

Haida Filter Pouch 100 Series View on Amazon View on B&H
The Haida 100 Series pouch is a fantastic alternative for those who find the official NiSi cases a bit too expensive. It utilizes an accordion-style design that expands to hold six filters. Each slot is lined with a soft microfiber material that helps prevent micro-scratches on the glass surface. I’ve used this pouch with both NiSi and Haida filters, and the fit is perfect—tight enough that they don’t rattle, but loose enough to pull out without a struggle. It’s significantly slimmer than the NiSi Caddy, making it a better choice if you’re trying to pack light for a long hike. The exterior is a rugged, water-resistant nylon that can handle a bit of drizzle. It doesn’t have a dedicated spot for the filter holder, but you can usually slip it into the front pocket if you’re only carrying four filters instead of six.

K&F Concept Filter Case View on Amazon View on B&H
For photographers who only carry a couple of filters—perhaps just a 10-stop ND and a single soft grad—the K&F Concept case is an unbeatable bargain. It’s a simple, three-slot folding wallet that offers basic protection against dust and minor bumps. It lacks the rigid structural support of the NiSi Caddy, so you won’t want to pack it at the bottom of a heavy bag where it could be crushed. However, its slim profile means it can slide into the laptop sleeve or a side pocket of your backpack with ease. The Velcro closure is secure, though I find it a bit noisy during quiet morning shoots. It’s an honest, functional piece of gear for those who are just dipping their toes into the world of square filters and don’t want to spend more on the case than they did on the holder.

MindShift Gear Filter Nest View on Amazon View on B&H
The MindShift Gear Filter Nest (by Think Tank) is a masterclass in organizational design. It features a removable internal “nest” with color-coded dividers, allowing you to quickly identify your ND filters versus your grads. The build quality is top-tier, using heavy-duty fabrics and a belt-loop attachment that is actually comfortable to wear. I find this particularly useful when I’m standing in the middle of a river or on a steep cliffside where there’s nowhere to set a bag down. You can pull the internal organizer out and leave the outer padded shell in your bag if you need to save space. While it doesn’t fit the NiSi holder as cleanly as the Caddy does, it offers the best overall protection and accessibility for the glass itself. It’s the choice for pros who need their gear to survive years of abuse in extreme environments.

Lowepro Filter Squad View on Amazon View on B&H
Lowepro’s Filter Squad is a robust, well-padded option that bridges the gap between a soft pouch and a hard case. It’s designed to fit 100mm square filters perfectly, but it also has enough flexibility to hold a couple of circular filters if needed. The internal dividers are quite stiff, which provides extra structural integrity—this is great if you’re prone to stuffing your bag tight. I’ve found the zippered closure to be very weather-resistant, which is a nice touch for coastal shooters dealing with salt spray. The “squad” organization means you can keep your holder, adapter rings, and glass all in one place. It’s a bit taller than the Haida, so check your bag’s dimensions, but the extra padding makes it a very safe bet for rougher handling during travel.

Frequently Asked Questions
Will these cases fit 150mm NiSi filters?
No, these cases are specifically sized for the 100mm system. If you use the NiSi 150mm system (for ultra-wide lenses like the Nikon 14-24mm), you will need the larger NiSi 150mm Filter Pouch. 150mm filters are significantly wider and taller, and attempting to force them into a 100mm case will likely damage the lining or the filter itself. Always check your filter width before purchasing.
Can I store the NiSi V7 holder inside the case?
Only the NiSi Caddy is specifically designed to hold the V7 holder comfortably alongside the filters. Other cases like the Haida or MindShift are built primarily for the glass plates. You might be able to squeeze a holder into the front pocket of a soft pouch, but it often puts too much pressure on the filters. For a complete kit, the Caddy is the best bet.
Are these filter cases waterproof?
Most of these cases are water-resistant, meaning they can handle light rain or splashes, but they are not fully waterproof or submersible. The NiSi Caddy and Lowepro Filter Squad have high-quality zippers and materials that repel water well. If you are shooting in heavy rain, I recommend keeping the case inside your camera bag or using a dedicated rain cover for your backpack to ensure the filters stay dry.
Do I need to keep the plastic sleeves on my filters?
I recommend removing the individual plastic sleeves once you have a high-quality pouch. Most modern pouches use microfiber or soft-lined dividers that are safe for the glass. Keeping the plastic sleeves makes it much harder to slide filters in and out, which can lead to fumbling or dropping them in the field. A good pouch is designed to replace those sleeves entirely while providing better protection.
How do I clean the inside of a filter pouch?
Dust and grit can eventually build up inside the slots, which can scratch your filters. Use a can of compressed air or a small vacuum attachment to blow out the slots periodically. If the lining gets particularly dirty, you can use a damp microfiber cloth with a tiny amount of mild soap to wipe the slots, but ensure the case is completely dry before putting your glass back in.
Final Verdict
If you’ve invested in the NiSi V7 system, don’t overthink it—the NiSi Caddy is the best way to carry your entire kit. It’s the only one that manages the holder and filters in one rigid, secure package. For those who want something lighter or are on a tighter budget, the Haida pouch offers nearly the same level of glass protection. Professional landscape photographers who prioritize workflow and belt-access should look no further than the MindShift Filter Nest.
