Buying Guide: How To Choose The Best Downspout Filter

1. Circumference

You should first consider the size of the downspout filters or the area they cover. Your gutters will be compatible with them based on this. An average downspout filter covers an area of 2 to 3 inches.

This is also perfect for gutters that are 5 inches wide. Additionally, circumference determines how much debris or water can pass through. Clogging is less likely to be an issue with larger rims.

2. Material

Material is also an essential factor to consider. The different types of filters include plastic, aluminum, stainless steel, and copper. Most metal filters are longer-lasting than plastic filters. For example, stainless steel doesn’t corrode or rust.

You may need a stainless steel or plastic filter if you live in a rainy area.

3. Color

The color of your filter is another element to consider. Although it is not such a crucial factor, it does play a crucial part in deciding which color complements your home.

  • Light-colored homes may benefit from white filters.
  • If your home is dark, choose a black filter.
  • For something generic, you should go for the classic metal types.

4. Design

There are two types of strainers: open or closed wedges. Strainers are usually installed inside gutters, whereas wedges are attached to or installed outside of gutters. Your choice should be based on your house design and personal preference.

5. Visibility

The downspout filter may appear unsightly. After proper installation and hiding, it is still possible to see them.

This may frustrate perfectionists. Thus, if you want better visibility, you should find the right product. Here are a few tips.

  • Choose a color that fits the texture of the house.
  • Select an underground filter if possible.

6. Type Of Extension

Identify the type of extension you need. Below are some aspects to consider.

  • Decide how many extensions you will need.
  • Choose between commercial and residential use.
  • Check if flexible filters are required.

You get the idea, don’t you? There are a lot of factors to consider. Therefore, you should research what you need and how you intend to use it.

7. Easy Installation

Lastly, you should consider the ease of installation. Current downspout debris filters are usually relatively easy to install. You can install many downspout filters without the use of tools.

Even if they do require screws, they are provided in the box. When you buy products like that, you won’t have to worry about installation.

Different Types of Downspout Gutter Guards

It is essential to understand the differences between downspout filters before choosing one. Here is a brief explanation of the various types of downspout filters.

1. Strainer Gutter Guards

Typically, strainers are made of plastic or aluminum. They are flat or rounded and installed within the gutter. 

This will allow water and heavy materials to fit into the filter. Ideal for downpipes.


2. Wedge Gutter Guards

The wedge type is made of plastic only, not metal. This is placed alongside the strainer rather than in the gutter. The filter features a slope rather than a round shape. In this way, water flows more smoothly. It’s especially useful in industrial settings.


3. Open Downspout Gutter Guards

The open downspouts are made of plastic or metal and feature a sloped filter that traps leaves and other debris. The quality of the filter depends on its type and size. They are easily visible when dirty, so you can clean them easily. The system usually overshoots if it’s not maintained properly.


4. Closed Downspout Gutter Guards

As well as aluminum, steel, galvanized, zinc, and copper, the closed inline clean-outs can be rounded or custom-made.

The debris is collected in a basket inside a box. Compared to open models, closed models retain more debris, so maintenance is reduced.

It is not recommended to use the micromesh in small and narrow spaces since it gets clogged very easily. Micromesh models can catch even the smallest debris.


5. Flexible Downspout Gutter Guards

As the name implies, they are pretty flexible and bendable.

Flexibility makes them easier to use. They are also quite cost-effective.

But there are some drawbacks. To make them so flexible and affordable, they are made from cheap materials, such as thin plastic.


6. Roll Out Downspout Gutter Guards

Roll-out downspout filters release water when detected. They roll up once water is removed. This makes them more convenient since visibility is not an issue. The functionality and appearance make them appealing.

If you have pets or children who run around the house, then it perfect solution because stepping in won’t be an issue.

This filter has some problems as well. Sometimes stones or dirt get stuck in the filters or pipes. To get it working again, you will need to fix it manually.


7. Flipper Or Hinge Downspout Gutter Guards

Finally, we have hinged or flipper downspout filters. You can adjust this filter at any time. They’re more expensive since they’re made of metals and other premium materials.

You can’t bend it, however. Apart from that, it works quite well.


Benefits Of Using Gutter Downspout Debris Filter

Best gutter guards prevent large debris such as leaves, sticks, and dead animals from getting into the gutters and clogging the system. These guards also have the following benefits:

1. Prevents Mold

It can be very difficult to remove mold if the moisture is not drained away. Here are a few hazards to watch out for:

  • The mold spreads like wildfire.
  • Your paint may have to be stripped off or special chemicals will be required.
  • Mold is also quite harmful to human health.
  • Getting rid of mold in your house is an expensive process.

Fortunately, downspouts aren’t as costly. The choice is yours – a few dollars for downspouts or thousands for mold removal.

In addition to preventing mold, it will also keep rainwater away from your house, keeping your home healthy and fresh.

2. Your Foundation Will Be Protected

Rainwater cools house temperature down for a while. The problem begins when it stays there for too long. Without a downspout, water ends up at your house’s foundation.

You might not notice it right away. When a large amount of rainwater soaks into your house’s soil for a long time, it softens its roots. 

A downspout directs rainwater to another area, securing the foundation of your home.

3. You Can Store Rainwater For Emergencies

A downspout can help you store water, in addition to protecting your house’s foundation and preventing mold. Simply place a barrel or a container at the end of the downspout. You can use it whenever you like.

Imagine that you have no water to wash your car. You will need this storage then. Also, you can water your garden with it. In any case, you’ll always save money on your water bill.

How To Unclog Gutter Downspouts

Do Downspout Extensions Work? Downspout pipes contain box-shaped structures that catch debris from rain gutters and prevent it from flowing into the underground drainage system.

The leaf, twigs, and other debris are caught in a filter, preventing the drain from clogging and damaging the house’s foundation.

Clean-outs installed about 2-4 feet from the ground make it easy to remove debris periodically. There are no safety concerns. If possible, empty the basket after every rainfall.
