What Is A Recirculating Microwave: Overview

What Is A Recirculating Microwave: Overview

Microwave ovens are a device for heating food. It uses a microwave, which is electromagnetic radiation similar to radio waves, to heat food.

Since it heats food, it tends to produce cooking odor, smoke, and moisture that rise from the cooking surface. Hence, some microwave oven comes with a ventilation system to prevent this.

This ventilation system is in two forms; convertible or exterior vent and recirculating or ductless vent. Moreover, the focus of this article is on the recirculating microwave.

A recirculating microwave uses high-speed fans to filter the exhaust from the microwave through a charcoal or grease filter and back into the kitchen.

In other words, it has a built-in exhaust fan that pulls air through the filter and exhausts that air back into the kitchen. This filter sits in a stainless steel cavity on the microwave.

Thus, you can remove and replace the filter regularly. Unfortunately, over time, the charcoal filter tends to lose its effectiveness.

Hence, you can replace the filter every six to twelve months. In addition, some microwave unit comes with a charcoal filter that helps to trap some particulate matter and odors.

Thus, a lot of the heat and moisture, as well as some particles, remain in the house. Also, some microwave units come with aluminum filters that trap grease.

Moreover, this venting option is quite popular in the over-the-range microwave. Nevertheless, some built-in microwaves also have this venting option.

Also, countertop models usually have recirculating venting system. Since the recirculating microwave does not require venting the air outside, it tends to be an energy-efficient way to improve the indoor air of your kitchen.

Although this venting option may not be as effective as other types, it is very good at clearing your kitchen air of most pungent cooking odors.

What Is A Recirculating Microwave: How It Works

What Is A Recirculating Microwave: How It Works

Recirculating filtration is one of the simplest forms of ventilation in a microwave oven. A lot of freestanding microwaves have this venting option.

A recirculating microwave is a built-in venting system that tends to recycle air via microwave vents. It pulls the air through some filters, including; charcoal, stainless steel, or carbon.

A charcoal filter is very common and easily replaceable. Hence, you can also make use of the other filter types.

However, this microwave has a simple working principle. The recirculating microwave has a fan that sucks the air inside the microwave through the filters, and then this air travels back into the kitchen.

This fan usually works at high speed to help remove cooking odor, smoke, or moisture from the kitchen. Then, all you need to do is to activate the recirculating filter.

To do this, you will locate the auto fan button on your microwave control panel and then click on it. Some models offer you the option to adjust your fan speed manually.

Hence, this type of microwave requires minimal maintenance. However, since most models make use of charcoal filters, it usually requires replacement every 6 to 12 months.

The replacement of the charcoal filter is very cheap. However, aside from replacing the filter, you must also regularly clean the grease filter.

This will help to ensure that the fan pulls as much air as possible. Also, you can clean the filter cover.

To do this, use soapy water and a rag. In the case of built-up grease, you can make use of a brillo pad for more scrubbing power.

While the fan is spinning, you should not block the stainless steel vent. This is because instead of filtering the kitchen air, it can, in turn, burn out the fan motor.

Factors To Consider

Installation Types

Most recirculating microwaves come with three types of installation. These installation types include; countertop, built-in, and over-the-range.
The countertop type is a freestanding microwave that allows you to place it wherever there is space on a countertop and close to an electric outlet. You can easily store this type in a cabinet or pantry when not in use.

The range type can double as a range hood. Hence, you can install this type above your cooktop or kitchen range.

This type has a fan and a vent system at the underside of the microwave that helps to remove smoke, odor, and moisture. In addition, some model tends to come with a temperature sensor or task lighting to light up the kitchen space.

The built-in type is usually costly and requires a professional installation. However, this type is usually incorporated into the kitchen design and enhances the overall beauty of the kitchen.

Size

In terms of dimension, most microwaves are usually 29 to 30 inches wide, 15 to 16 inches deep, and 16 to 18 inches tall. Hence, you need to measure your space to determine the one that will suit your needs.

Most countertop types can take up a lot of space, so you need to measure the length, width, and height of the top of the counter to the bottom of the cabinet.

Over-the-range types require you to measure the distance from the floor to the bottom of the microwave, which is not more than 54 inches. This is to ensure safety as well as provide easy access.

This height allows the space between the cooktop and the microwave to be 18 inches to ensure an adequate cooking room. Also, most building codes require a clearance of 36 inches between the cooktop and the bottom surface of a shelve or cabinet.

Capacity

The capacity of the recirculating microwave depends on your needs. There are small microwaves that can suit a small kitchen and a spacious one that is enough for a large family’s needs.

The capacity of the microwave is usually measured in cubic feet. Hence they range from as small as 1cu. ft. to as large as 2cu. ft.

Power

The power capacity of a microwave is usually measured in watts. Microwave power tends to range from 700 to 1500 watts.

Hence, a microwave that has lower wattage tends to emit less power. Therefore, this type usually helps cut down the power consumption cost.

Those with higher wattage tend to emit more power and are usually more expensive. Hence, they can heat food more quickly and thoroughly.

This type often has more cooking capabilities than those with lower wattage.

Venting Type

Most recirculating microwave tends to have a recirculating venting system. This venting system allows air to pass through a filter before blowing that air back into the kitchen.

Most over-the-range microwaves have this type of venting system. Also, countertops and some built-in models offer this type of venting system.

Fan Speed

Most recirculating microwave usually features two to four-speed fans of ventilation. This recirculating fan has a speed that ranges from 300 CFM to 400CFM.

Some models even offer a lesser speed. Also, some microwave models allow you to adjust the fan speed manually so you can set it to your desired speed.

Filters

Most recirculating microwaves often have different types of filters. These filters include; charcoal, stainless steel, or carbon.

A charcoal filter is the most common type of filter, and it is easily replaceable. Some models also come with a grease filter that helps to remove odor and smoke.

Also, some models come with both charcoal and grease filters. Filters are easily removable from the microwave.

Thus, they require minimal maintenance by cleaning or replacing them regularly.

Turntable

Most microwaves, if not all, come with a rotating turntable. This turntable tends to rotate while the food is heating.

The rotating turn table helps disperse the heat evenly throughout the food. Also, it helps to prevent burning.

The turntable often varies in size, and it depends on the size of the microwave itself. Most recirculating microwaves offer glass turntables.

Material

Most recirculating microwaves have a stainless steel exterior, with some models offering a stain-resistant body. This helps to provide the durability of the microwave.

Also, they often come with glass doors. The interior materials are usually easy to clean, with some models offering a ceramic interior.

A ceramic interior can easily clean and wipe off any stain.

Other Features

Recirculating microwave tends to offer other features. They include; LED lights, auto preset settings, child or safety locks, timer, signal alert, sensor cooking, and so on.

What Is A Recirculating Microwave: Pros And Cons

Pros

Exhaust Effectiveness

A recirculating microwave pulls air through a filter and exhausts that air back into the kitchen. In addition, it uses filters to trap odors, smoke, and moisture.

Since they don’t vent the air outside, they tend to offer an energy-efficient way to improve the indoor air quality of the kitchen.

Vent Installation Cost

When it comes to installation, the recirculating microwave is easier and cheaper to install. This is because it does not require ductwork or an external venting cap.

It also does not require you to pierce into the wall, ceiling, or roof. Instead, you can easily install the recirculating microwave on the interior wall.

Also, you can easily move it relatively. It does not require a lot of costs since you will not be paying to cut through the wall to install the vent.

Odor Control

A recirculating microwave may not have removed the smoke and steams from the kitchen, but they help to mitigate odor. They tend to achieve this with the aid of the filter.

The filter helps in clearing the most pungent odor in your kitchen. Also, it further provides better air quality in the kitchen.

Vent Requirement

Since the recirculating vent does not have exterior components, they don’t require a lot of venting requirements. However, some local building codes specify the minimum distance between the microwave and the cooktop.

Also, most types of microwaves usually come with a manual containing the installation requirement.

Cons

Poor Air Quality

Though the recirculating microwave helps to deal with steam, smoke, and moisture, they don’t offer a better air quality than the exterior venting.

This is because the exterior vent removes those particles away from the kitchen. Therefore it also expels them away from home.

Loose Effectiveness

Since the microwave helps to remove odor via a filter, this filter tends to lose its effectiveness over time, especially the charcoal filter.

The charcoal filter often needs replacement between six to eight months. Hence, it is not costly to replace them.

Requires Regular Maintenance

The filter of the microwave usually requires minimal maintenance. However, for charcoal filters, you need to replace them periodically.

Generally, this filter tends to last for six to twelve months. Moreover, frequent microwave cooking can reduce the filter’s lifespan.

Aluminum filters often require regular cleaning. You can clean it with soapy water that contains a degreasing detergent with a rag to clean it.

You can also wash some grease filters in a dishwasher, but you need to confirm if it is dishwasher safe from the manual.
