Stetzerizer Vs. Greenwave

Dirty electricity is a problem that affects many homes but is something that not many people know about.

Luckily you can buy dirty electricity filters that drastically reduce its presence in your home. Two of the industry leaders are:

So which is better, Greenwave or Stetzerizer? Greenwave filters are the better choice for a number of reasons, including design, price, and compliance ratings. Of the two, Greenwave provides higher quality dirty electricity filtration and provides the user with more clean electricity. 

Before moving on to the reviews, it’s worth understanding what dirty electricity is, and why you need to install a dirty electricity filter in your home. Knowing this will make the reviews clearer and will allow you to make a more informed decision.

What is Dirty Electricity?

When electricity is supplied to our homes, it comes in at a certain voltage, such as 110 or 240. However, the overall quality of the electricity can be affected by a wide range of factors, and these in turn impact how efficiently your appliances run and how much energy is given off in the form of EMF radiation.

Clean energy is considered efficient and safe and is the standard you want in your home. Dirty electricity is when this is impacted by different factors and is not what you want in your home. Dirty electricity can be caused by the following things:

    • Dimmer switches for lights
    • TVs
    • Wi-Fi routers and modems
    • High-demand devices, such as hairdryers, refrigerators, blenders, and computers
  • Smart meters and other smart appliances
  • Power pylons near the home
  • Cellphone masts

Essentially, dirty electricity is any voltage deviation from what’s considered “normal”, which is different depending on where in the world you live. The frequency of mains electricity is 50Hz, and any voltage deviations can impact this.

Dirty electricity is believed to be a factor in causing such health conditions as ADHD, insomnia, cancer, diabetes, headaches, and more (source). Some people are particularly sensitive to EMF radiation anyway, and dirty electricity only makes this problem worse.

What to Dirty Electricity Filters Do?

Dirty electricity filters do exactly that: they turn dirty, unusable electricity back into good quality power for your home.

They work by plugging into a mains outlet and then filtering the power. They do this by taking in the electrical current, as any device does, filtering it, and then returning it to the power supply.

A dirty electricity filter works in a frequency range of 4Hz to 150Hz, which research has shown is the most harmful range of frequencies to the human body. Doing so means there’s less EMF radiation in your home, which brings with it a number of health benefits.

Stetzerizer Filter Review

The Stetzerizer (also known as Stetzer) dirty electricity filter is well known on the dirty electricity market and is considered one of the industry leaders. It’s designed to filter what it calls “trash” (high frequency current) from your mains supply, thereby turning it back into usable electricity.


The Stetzerizer is really easy to install; all you need to do is plug it into an electrical socket. However, the manufacturers advise you need a dirty electricity meter to take readings to ensure the product has worked. You don’t get a meter in the pack, so this means having to pay out more money.

The manufacturer recommends positioning your filters in a strategic way throughout the home, which will vary depending on your needs. They recommend at least 2 near a TV or computer, and up to 6 near your power input panel.

As you can see, this means you’ll be needing quite a few Stetzerizer filters. In fact, the manufacturers say you’ll need up to 20, but this will vary depending on the size of your home and the extent of your problem.

So the installation of the product is incredibly easy. What’s not pleasant, however, is the idea that you’ll need so many in your home to effectively filter dirty electricity, as this is going to cost you quite a bit of money.


When it comes to the price of a Stetzerizer filter, they don’t come cheap. In fact, they’re currently going just under $30 on Amazon. Considering they advise you need up to 20, you could be paying nearly $600 to kit out your home! But is it worth it?


Overall, the Stetzerizer dirty electricity filter does do a pretty good job of filtering power in your home. When tested with a high frequency meter, readings dropped below 30, which the meter states are an acceptable level. However, the Stetzerizer can get drowned out by a high level of dirty electricity, which is why the manufacturers say you might need more than one in each location.

The bottom line is that the Stetzerizer does an average job considering the price and the fact that you’ll need so many to truly improve your home’s electricity quality. Considering the amount of money you’ll need to pay to get the system working, it’s worth costing up the project and then looking at alternatives.

Greenwave Filter Review

Greenwave is another big name in the dirty electricity filter industry. Their product is much more sleek and modern looking, and while this doesn’t have any direct impact on performance, it’s definitely a more attractive product to have in your home.


Greenwave is also really easy to install, and simply requires plugging into a spare electrical outlet. However, one of the best features of the Greenwave filter is that it has an electrical outlet installed. This means that, unlike the Stetzerizer, you don’t have to sacrifice a spare socket.

While Greenwave also advises that you’ll need several of their filters in a room, they state you’ll only need 2 for an average room. They say this can increase to 4 filters depending on the concentration of dirty electricity, but this is already fewer filters than Stetzerizer.

Similarly, Greenwave advises you’ll need up to 16 for a full home, and this is only in cases of high levels of dirty electricity. This means that you’ll be spending less money, simply because you’ll need fewer filters in your home.

The only time Greenwave advises a high number of filters in a room is in classrooms. However, this is mainly because children are much more sensitive to EMF radiation, along with there being more people in the room. For an average home, the recommendation of up to 2 per room is pretty cost-effective.

Read an even more detailed review of the Greenwave filters which will answer all your queries regarding its effectiveness and the number required to protect your home.


An individual unit on Greenwave’s website will cost you $30. This puts it at a slightly more attractive price point, but realistically this is worth it if only for the superior design. After all, it’s only a dollar’s difference and you’ll be needing fewer filters anyway, so you’ll be saving money overall.

Similarly, Greenwave also offers multi-packs of filters on their website, and these come with a considerable discount attached. In fact, if you buy more than 8 filters in a single transaction, the price drops to $28 per unit, which is cheaper than the Stetzerizer.


When tested with an EMI meter, Greenwave filters showed up to a 90% reduction in dirty electricity and high frequency readings. This is a considerable difference and makes it a much more efficient product.

The very fact that you need fewer units in your house shows it’s a more effective product. However, like Stetzerizer, Greenwave advises buying a meter to assist with installation, which is also going to set you back a bit more money.

Which is better, Greenwave or Stetzerizer?

Here is a handy chart to help you compare the 2 filters:

Amount needed in homeUp to 16Up to 20
Price$20-30 per unit$28-30 per unit
Range of clean electricity50-60Hz60Hz
Safety compliant?Yes (both USA and Canada)No
Extra electrical outlet?YesNo
Worth it?YesMaybe

As you can see from the table, Greenwave is the clear winner for a number of reasons. For example, its extra electrical outlet is a small but incredibly useful addition that makes the product more convenient.

One area where the Stetzerizer filter wins is on price, as it’s cheaper per unit than the Greenwave. However, once you price up the project, you’ll inevitably find that Greenwave comes out on top. If nothing else, the company offer discount packages on bulk orders.

Overall, the Greenwave filter is a more powerful and effective device that’ll do a much better job of filtering dirty electricity in your home. It’s easy to use and safety compliant, and will provide noticeable results almost instantly.

Get the Greenwave filters on the official website (recommended). They’re also available on Amazon.


While the Greenwave dirty electricity filter definitely comes out on top, the Stetzerizer might still be more suitable for some people. However, if you’re looking for a sleek and effective product, then the Greenwave is definitely the one for you.

Reducing levels of dirty electricity in your home is definitely an important project, and Greenwave helps you do this.
