6 Best Sprayer Strainers For Preventing Nozzle Clogging That End Frustration
Prevent frustrating nozzle clogs with the right filter. We review the 6 best sprayer strainers for a consistently clean and even spray application.
There’s nothing more frustrating than being halfway through a spraying job when a nozzle sputters to a stop, ruining your spray pattern and wasting your time. You fiddle with the tip, trying to clear the blockage, while your carefully mixed solution drips down your arm. The right set of sprayer strainers isn’t just a piece of equipment; it’s your insurance against this exact moment of peak frustration.

Why Sprayer Strainers Are Your Best Defense
Think of sprayer filtration as a series of gates, each one finer than the last. A single filter is a single point of failure. A layered system, however, ensures that debris is caught systematically, from large particles at the tank to microscopic ones right at the nozzle.
This system starts with a coarse filter in the tank opening, followed by a suction strainer before the pump, an in-line strainer after the pump, and finally, small tip strainers at each nozzle. Each stage protects the next. The suction strainer saves your pump from damage, the line strainer protects your boom components, and the tip strainers provide the final defense for the delicate nozzle orifice.
Ignoring this layered approach is the most common mistake I see. People either rely on a single filter or skip one entirely, usually the suction strainer. This inevitably leads to clogs, pump damage, and inconsistent application, which can mean patchy weed control or uneven fertilizer coverage.
TeeJet AA122 Line Strainer: The All-Rounder
If you only have one in-line strainer on your sprayer, it’s probably a version of this one. The TeeJet AA122 is the workhorse of post-pump filtration. It’s installed between your pump and the spray boom, acting as the primary defense for all your nozzles.
Its strength lies in its simplicity and versatility. The clear bowl lets you see when it’s getting dirty, and the unscrew-and-rinse cleaning process is straightforward. You can get screens for it in various mesh sizes, but the 50 mesh (blue) or 80 mesh (red) are the most common and useful for general-purpose spraying. A 50 mesh is perfect for most herbicides and liquid fertilizers, while the 80 mesh offers finer filtration for products that are more prone to clogging.
This strainer isn’t fancy, but it’s incredibly reliable. Its heavy-duty polypropylene body handles most farm chemicals without issue. For a hobby farmer with a boom sprayer for a few acres of pasture or a large garden, this is a non-negotiable component that provides excellent protection for a very reasonable cost.
Hypro 3350 Suction Strainer: First Line of Defense
The suction strainer is the unsung hero of your spray system. Placed on the intake hose between the tank and the pump, its job is simple: protect the pump. Your pump has tight tolerances, and even small debris like a stray leaf fragment or a clump of undissolved powder can cause serious damage to its diaphragms or rollers.
The Hypro 3350 is a fantastic example of a robust suction strainer. It has a large surface area, which means it can catch a lot of gunk before it starts to restrict flow and starve your pump. Starving the pump, a condition called cavitation, can destroy it in minutes. This strainer prevents that.
Don’t ever pull water from a pond, creek, or even a questionable storage tank without a suction strainer in place. It’s the difference between a pump that lasts for years and one that dies mid-season. It’s your first and most important line of defense.
Banjo T-Line Strainer: For Easiest Clean-Outs
Cleaning strainers is a necessary chore, but it doesn’t have to be a messy one. This is where the Banjo T-Line Strainer shines. Its brilliant design places the filter bowl on the bottom of a "T" fitting, allowing you to shut off the flow, unscrew the bowl, and clean the screen without disconnecting any hoses.
This might sound like a small detail, but it’s a huge quality-of-life improvement. On a conventional in-line strainer, you often have to wrestle with stiff hoses, leading to spills and frustration. With the Banjo T-Strainer, you can check and clean your filter in under a minute, making you far more likely to do it regularly.
This is the strainer I recommend to anyone building their own sprayer or upgrading an existing one. The time and hassle it saves are well worth the slightly higher initial cost. It’s a perfect example of smart design making a recurring task simple and clean.
Greenleaf Combo-Jet: Integrated Nozzle Protection
Even with perfect filtration upstream, tiny particles can still make their way to the nozzles. This is especially true if you have older hoses that might be degrading internally. The Greenleaf Combo-Jet system solves this by integrating the strainer directly into the nozzle cap assembly.
This design combines the nozzle body, cap, gasket, and strainer into a single, easy-to-handle unit. The strainer is a cylindrical screen that sits directly behind the spray tip, providing last-chance protection right where it matters most. It’s the final gatekeeper, ensuring that anything reaching the tiny orifice of your spray tip is clean fluid.
The convenience is a major benefit. When you do get a clog, you can quickly twist off the cap, rinse the small screen and tip, and be back to spraying in seconds. For anyone tired of fumbling with tiny, separate strainer screens that always seem to get lost, this integrated system is a game-changer.
Arag 324 In-Line Filter: High-Flow Capacity
For those of us with slightly larger setups—maybe a 50-gallon tank and a pump that moves more than 5 gallons per minute—a standard line strainer can become a bottleneck. The Arag 324 is a high-capacity filter designed to handle higher flow rates without causing pressure drops.
The key is its massive filter screen. A larger surface area means it can trap more debris before it needs cleaning and allows liquid to pass through with less restriction. This is crucial for maintaining consistent pressure across your entire boom.
While it might be overkill for a small ATV spot sprayer, it’s the perfect choice for a 3-point hitch sprayer covering several acres. If you find yourself cleaning your standard line strainer multiple times per tank, upgrading to a high-capacity model like the Arag will significantly reduce your downtime.
Fimco Tip Strainers: Affordable Last-Chance Filters
Sometimes, the simplest solution is the best. Fimco tip strainers are small, inexpensive, drop-in filters that sit inside the nozzle body, right behind the spray tip. They are the most basic form of last-chance filtration you can get.
They aren’t fancy. They are just a small mesh screen, often color-coded to match the mesh size of your main line strainer. The rule of thumb is simple: your tip strainer mesh should be equal to or finer than your main line strainer mesh. For example, if you use a 50-mesh line strainer, use 50-mesh or 100-mesh tip strainers.
Because they are so cheap, you can keep a dozen on hand. If one gets hopelessly clogged with a stubborn chemical residue, you don’t have to waste time scrubbing it—just toss it and drop in a new one. They are an essential, low-cost final guard against frustrating tip clogs.
Strainer Maintenance for Clog-Free Spraying
The best strainer in the world is useless if it’s already full of junk. Consistent maintenance is the secret to clog-free spraying. It doesn’t take long, but it needs to become a habit.
Make it a rule to check your strainers at the end of every spray day. When you’re rinsing your tank, take a few extra minutes to open up your suction and line strainers. A quick rinse with a hose is usually all it takes. For stubborn residue, especially from wettable powders, an old toothbrush is your best friend.
Pay attention to what you find. If your line strainer is always full of large debris, it means your tank-fill or suction strainer isn’t doing its job. If your nozzle screens are clogging but the line strainer is clean, you might have residue breaking loose from inside your hoses. Your strainers don’t just prevent clogs; they tell you a story about the health of your entire spray system.
Ultimately, a reliable sprayer depends on a smart, layered filtration system, not just a single part. By matching the right strainers to your setup—from the suction hose to the nozzle tip—you trade a few minutes of maintenance for hours of saved time in the field. Stop fighting clogs and start spraying with confidence.
