Rfc3700a water filter is the perfect example of fulfilling all your requirements in your limited budget range. The reason why this one is trustworthy is that experts have tested and approved it based on the following key features that it offers.

Let us see what they are.

Filtration Quality

When you buy a water filter, your major concern is always how good it filters out all the harmful viruses, bacteria, and other contaminants from the water.

Thanks to OnePurify RFC3007 that you will never have to worry about the quality of the water you drink. The filter features activated carbon blocks for optimal filtration performance so that no particulates are left behind.

With a 0.5 micron size, the smallest particles of sediments, silt, dirt, and debris are removed along with chlorine, lead, mercury, metal, cyst, microbes, and other harmful contaminants. The reduction of chlorine also improves the taste and reduces odors in the water.

Filter Life And Capacity

Everyone wants their filters for long-term use and that is where this refrigerator filter excels others. The filter is very easy to use yet it is giving a hard time to its competitors. Most of the expensive filter brands are offering the same filter life as this one that is 6 months.

So, why spend more when you can get the same quality within your range. The filter comes in three different packages. If you buy a 1-pack, it will last for 6 months. 2-pack filter lasts for a year and a 3-pack filter lasts for 1- ½ years that saves you a lot more than other brands.

Warranty And Certification

The warranty for this filter is uncertain, but you can directly contact the manufacturer for the details. However, OnePurify RFC3007 is fully certified and approved by WQA for making your water tasty, refreshing, and safe to drink.

It is manufactured under an ISO9001 FDA registered facility to ensure the users its quality. A water filter is only considered worthy when it is tested and approved by renowned authorities and organizations for water quality. In terms of efficiency, this filter will always have your back.


Because these filters are designed to fit in your refrigerators, they are designed with simplicity so that you can use it with any of your refrigerator brands.

Although it works best with Filter 1, it is also compatible with EDR1RXD1, W10295370, W10295370A, WRL767SIAM, WRS322FDAB, WRS325FDAB, WRS526SIAH, WRS537SIAB, P4RFWB, P5WB2L, W10276924, W10291030, PS2378001, 9930, 46-9930, 469930, and 9081.

Now, you don’t have to find a specific filter that is compatible with your refrigerator model because this one fits all.


Let’s face it! Installing and replacing your refrigerator and dispenser filters is challenging. Most of the time, people fail to understand where the filter is placed.

Depending on the model of your fridge, your filter can either be at the backside of the bottom tray or the right corner of the refrigerator. Once you find the filter, the rest of the process is smooth. Just twist the filter and remove the cartridge out.

Place the new one inside and twist it on the opposite side to close tight.


When we talk about all the good points of a product, you must know the drawbacks as well because perfection is just an illusion. One thing we found exceptional in this filter is the ratio or its positive points to the drawbacks.

The only issue that we found in this filter is leakage. If the filter is not fitted in place, it can leak inside the refrigerator creating a mess. Make sure that the filter isn’t cracked or damaged at the time of installation.

Do not push the filter too tight or leave or too loose as it will leak in both cases.

There are many popular brands out there that are far more expensive than this one yet they perform at the same level as RFC3700. That makes it quite clear for the customers that they should go for the product that isn’t demanding extra.

Buying Guide for Refrigerator Water Filter

Buying a refrigerator water filter can be a challenge if you are new in the game, however, we have made it easy for you. The mistake that a lot of people do it trust whatever they see at first glance and buy it to save time.

Remember, you are doing no good for your time and money because rushing these things never end up well. We have compiled a short buying guide carrying all the important things to consider to check before clicking the order placement button.


Compatibility is the key to perform when it comes to choosing the right refrigerator water filter. Buying a filter that isn’t designed for your ridge model won’t fit right. Thus, the performance will not be as expected.

There are brands that have successfully manufactured multi-compatible filters. You can easily search for these types of filters so that you won’t have to worry whether you are using Samsung, LG, or GE refrigerators.

Flow Rate

The better the flow rate the better the performance of your filter will be. For common household usage, a flow rate of 0.5 GPM works best. Higher flow rates are also available, but you have to make sure it is balanced with the current flow rate of your main water line.

If the water pressure exceeds the pressure of your water line, it can result in a burst in the filter. Make sure you measure the flow rate and water pressure of your main supply before choosing a filter.

What It Removes

The filtration media is another important thing to consider. Not many of you will understand this, but it is easy. You have to ask the manufacturer about the material of the filter.

The best refrigerator filter is made up of activated carbon blocks, coconut shell carbon, or both. You can also choose ceramic filters. Make sure the filter is capable to remove VOCs, THMs, hormones, heavy metals, pesticides, and other chemicals along with lead, mercury, chlorine, and sediments.


Your health depends on the quality of water you are using. Not only for drinking, but you use water for almost everything. You need water to make tea, smoothies, brew coffee, prepare baby food, and in cooking.

Never count on a filter that doesn’t have any authorized certifications such as NSF, FDA, or WQA. A certified refrigerator water filter means you are using a widely trusted product.

Filter Life

Another important thing to consider before buying a refrigerator filter is its life. You cannot change your refrigerator filter every month, especially if it is placed in the right corner of the lower compartment.

Choose a filter that has at least a 6 months life so that replacements would be easier and lesser.


When it comes to the cost of refrigerator water filters, you cannot imagine the lowest and highest range of their prices. You can get these filters at a very cheap price at the cost of your health and you can also spend your savings just for the advanced features.

None of these seem really worthy right? This is why be very careful when choosing a filter. Do not get enticed by too low rates and don’t fall for the glamorous advertisements of expensive brands.

Stick to your budget and search for the products closely related to your requirements at an affordable price.
