Last Updated: 25 March 2020

Here is a rating of the best network filters relying on expert evaluation and reviews from real customers. This guidance is intended to aid you to select the most suitable model for your home or office, taking into account your strictest demands and wishes. With so many rivals in the world equipment market, you will be able to choose the appropriate product from the best manufacturers.


Depending on the level of security provided, the surge protectors are divided into the following models:


They provide the necessary security features. These are inexpensive, simple devices that are used to protect simple household appliances.

Home / Office

These are universal devices with an optimal combination of price and quality. Such surge protectors can be used with most household appliances.


This is professional equipment for sophisticated electronic devices. It provides maximum protection but is much more expensive. Such devices can be used to protect especially sensitive to voltage drops expensive appliances, for example, home theaters.


A modern consumer, before choosing from a catalog of photos and buying this device, carefully examines ratings and customers’ reviews. It is easy to purchase any product in the online store now because every seller takes care of maximally providing information about the characteristics of each item in its range. Thus, what are the sacrosanct things to pay attention to?

What Equipment Do You Need To Protect?

For a computer or laptop, you should purchase a device equipped with varistors and capacitors. Capacitors “take” excess energy with increasing voltage and give it back while reducing it. The device can protect computer equipment from pulsed and high-frequency interference. For a TV, a 250 V version is sufficient. This is enough to preserve the device with a rated power of 130 V, including all additionally connected things. For expensive LCD models, you must select filters with maximum stability. When using a stabilizer, the need to connect a surge protector is eliminated. For household appliances (refrigerator, microwave, multi-cooker, and other tools), there are enough models that fit the total power. In this case, there are suitable basic options, reliable and relatively inexpensive.

How Many Outlets Do You Need?

Surge filters except single portable devices are designed for the simultaneous connection of several gadgets. The more outlets on the screen, the more electrical appliances can be attached.

How Long Should The Cord Be?

Long cable provides mobility and increases the area on which you can use the connected device. Long cables are convenient in rooms with a large area for building tools, vacuum cleaners, and other portable equipment. But in small rooms, there is no need to take an extension cord “with a margin”; it suffices to limit it to models with an average cable length; otherwise, it will interfere and get tangled. The most common lengths of devices are 1.5; 1.8; 3; 4; 5; 10 meters. A too long cord is also undesirable – the efficiency of the device will decrease. What happens when the capacity of is reached? Each filter has a maximum power that should not be exceeded. Usually, it is 3500 watts. This information is usually indicated near the “ON / OFF” switch or on the bottom of the filter. Improper use of a power surge protector can cause a fire.

What About Warranty?

This parameter is important. The longer the warranty period is, the better it is! If the manufacturer is confident in the quality of the device, then the warranty will be great. Some manufacturers give a guarantee of up to 5 years, so try to choose a smart surge protector with a guarantee of at least three years. In this case, if the filter fails due to a voltage surge, the device will be subject to replacement under warranty.

Other Features To Consider

To choose the right office or home surge protector, pay attention to the following:

  • Total Energy Dissipation: the parameter is calculated in Joules, and the higher its value is, the better the device copes with impulse noise;
  • Maximum Load Current: the parameter is calculated in amperes, and the higher its value is, the more efficiently the device will cope with voltage drops in the mains;
  • Maximum Capacity: this parameter is denoted in watts and determines the total power consumption of electrical devices connected to the filter.

Distance Between The Sockets

It should be sufficient to have enough space for an adapter.

Contact Plug

In models of bona fide manufacturers, they are made of high-quality non-ferrous metal. This is checked with a magnet. Cheap metal will often overheat, which is fraught with damage to the case and burning of contacts.

Number Of Switches On The Surge Protector

It can be in a single for the whole house surge protector or individual for each outlet. In the second case, the advantage is the ability to control the supply of electricity to every single device.


A model with USB, sockets with different standards, the light indication of workflows simplifies the operation of the device.


The whole home device is a device that everyone can afford, and it is an essential thing in any home. The cost varies depending on the manufacturer, the degree of protection, maximum power, and additional features. If there is no need for a high degree of security, and if power surges are rare in your home, then there is no point in overpaying. In the case of constant electrical noise, the safest one with a high degree of protection is indispensable. It should be noted that it is better not to be limited to a cheap model, as it is well known, “the miser pays twice.”


Our choice is APC Back-UPS Pro, as it is an interesting multifunctional UPS with all the necessary types of protection that a home user may need. Thanks to smart sockets and the presence of the screen, it provides increased usability and high information content. Also, it is possible to install inexpensive alternative batteries, and the APC service makes repair and replacement of components without any problems.

The best choice is the device that will save your equipment from interference and power surges in the mains. Externally, it may look like an ordinary power strip, but the difference is that it is equipped with a particular unit, mitigating the effects of sudden surges of electricity.

Only in an ideal world, the current in an electrical outlet has only two states: it is present or not. In reality, the "behavior" of electric power has an "analog" unpredictable character, unpleasantly surprising every time you expect it the least. There are many reasons why the “mains powered” can differ from the norm and even go beyond the standard deviations. So, the evening voltage in the network – when each outlet of each apartment switches on a kettle, a TV or a computer – is significantly different from the voltage at night or daytime with a minimum load.

It suffices to say that, only a few people know this fact, but surge protectors can wear out. For about two years, they let through a possible number of Joules and fail. This is especially dangerous because the operation of these devices that have expired can end in fire. The service life can be roughly determined based on the duration of the warranty given to this device. If the manufacturer is confident in the quality of its filter, then the guarantee will be substantial, sometimes reaching even the mark of five years, and in the event of an instrument failure due to a voltage jump, the product will be exchanged. If the model does not have a warranty period of three years, it is better to look for a more reliable device.

  1. Surge protection. They occur when equipment is turned on and off, for example, a perforator or a washing machine in a nearby apartment.
  2. Protection against voltage pulses. They are short-term, formed as a result of lightning strikes or improper grounding.
  3. Protection against noise interference. These are radio frequency and electromagnetic interference from home appliances and radio stations operating nearby.
