Are recirculating vent hoods effective?

Yes. A recirculating range hood works beautifully, the same way as a ducted range hood. The main difference is that rather than the air getting exhausted to the outside, it passes through a filter, and then recirculated back into the house.

Are ductless vent hoods good?

In general, a ductless range hood is better than no range hood. Ductless range hoods can be installed on your wall, over a kitchen island, or inside a custom range hood. They are also a cost-effective option for your kitchen, since you don't have to pay a contractor to install ductwork.

Do ductless range hoods remove smoke?

A ductless (or ventless) range hood does not vent out of the home, instead, it carries the debris and smoke form the air and filters it through a charcoal or carbon filter before releasing it back into the room. While many times this method is not as functional as a vented hood, it does work.

Are vented hoods actually useful?

In addition to whisking away unwanted odors, vent hoods remove moisture and grease, as well as carbon monoxide, nitrogen dioxide, and other pollutants that cooking can release into the air.

Can you use recirculating hood with gas range?

We don't recommend venting your gas stove with a ductless hood. A ductless range hood merely recirculates your kitchen air. The air moves into your hood through charcoal filters and back into the kitchen. A ductless range hood can't get rid of a lot of the ultra-fine particles that are harmful to your health.

What is a Recirculating Range Hood?- What is a Ductless Range Hood?

What's the point of a ductless range hood?

A ductless range hood works by sucking greasy kitchen air through mesh and baffle filters. Once the air passes via these filters, it moves through carbon filters that can trap dirt and then neutralize strong cooking odors.

Why does a gas stove not need to be vented?

These pollutants include carbon monoxide, nitrogen dioxide, and formaldehyde. The study found that gas burners are often used without the support of a vented range hood and this greatly increases the risk of deadly gas buildup.

Do vent hoods need to vent outside?

Do range hoods have to be vented outside? No; range hoods without a duct, or ductless range hoods, can recirculate air back into your kitchen. However, to clean your kitchen air most efficiently, purchase a ducted range hood. Rather than relocate the cooking exhaust, it will evacuate it from your home entirely.

Do I need a hood over my stove?

Yes. A range hood keeps cooking exhaust, chemicals, and smoke out of your kitchen. It improves your indoor air quality and streamlines your cooking experience.

Do all kitchen vents need to be vented outside?

Gas stoves produce a lot of heat and harmful contaminants, so we recommend venting hoods over gas stoves to the outside. Electric stoves aren't as powerful so you can use a ventless hood in most cases. But we recommend a hood that is vented to the outside to keep your air clean and fresh.

Can you replace a ducted range hood with a ductless range hood?

They are typically ducted hoods that can be converted to ductless using a recirculating kit. A recirculating kit attaches to the top of your range hood. It vents the air coming through your range hood through charcoal filters and back into your home.

What is the highest CFM for ductless range hood?

The best ductless range hood is the PLJW 185. It is a versatile convertible range hood that is quite powerful. At just five inches tall, it runs at an impressive 600 CFM – the most powerful range hood on the market for its size.

How do you clean a ductless range hood?

Use a nylon or non-abrasive brush to remove grease, smoke deposits and build-up. Allow to sit for 3-5 minutes for the cleaner to penetrate tough buildup. Rinse filters with hot water and allow to air dry. Once dry, return filter to the range hood.

How do you vent a kitchen with no outside access?

Do downdraft vents work?

Because of their design, downdraft vents work harder than updraft systems to remove air, and are usually ineffective at drawing steam, odors and smoke from burners that are farthest away, and from tall stockpots.

Is 400 cfm enough for a range hood?

To power your range hood, you need at least 100 CFM for every 10,000 BTUs of your stovetop. For example, a 100,000 BTU stove needs at least a 1000 CFM range hood. For electric stoves, multiply the stove width by 10. So, for a 42” electric stove you want a range hood with at least 420 CFM.

Can you have a cooktop without a vent?

Although it is a desirable option, a regular kitchen cooktop does not need to be vented and exhausted to the outside. A downdraft cooktop and grill must be vented from the kitchen to the outside, following manufacturer's specifications.

Should gas ranges be vented?

Proper ventilation for cooking appliances is very important for indoor air quality. The range hood should ventilate to the outside and not simply recirculate and attempt to filter the cooking fumes. This is especially important with gas ranges.

Do I need a downdraft on my gas cooktop?

Some stoves come with built-in downdraft vents that rise up from the back or center of the cooktop when a burner is lit. Like updraft hoods, downdraft units must be vented to the outdoors or they are ineffective. On a gas stove, a malfunctioning downdraft vent can allow dangerous carbon monoxide to remain in the air.

What is the difference between ductless and duct range hood?

The major difference between the two is that a ductless range hood, which is more common in most kitchens, uses a fan or blower motor to pull all the grease and smoke out of the air, then recirculates it. A ducted range hood, on the other hand, vents all the bad air straight to the outside.

Is 300 CFM enough for a gas range?

The suggested CFM requirements for cooktops: “Regular” gas cooktops output 40,000 BTU's. To calculate your gas stove's BTU, add the power of each burner and divide the total by 100. So a “regular” gas system would need a 300 CFM fan.

How many CFM for a range hood do I really need?

To meet the recommended CFM requirements, you'll need a range hood with 250 CFM. Island hoods – 150 CFM for every linear foot of cooktop. Due to the open nature of a kitchen island stove, you need extra power. As a general rule of thumb, for the same 30” cooktop, you'll need a range hood with 375 CFM.

What size hood do you need for a 30 range?

For example, for a 30” range, a 36” hood is ideal. Then, subtract 2” and you get 34”. So a 34” hood insert or larger is a great fit for a 30” range. For outdoor applications, go with an insert two sizes larger than your range.

What is a recirculating Rangehood?

Unlike a ducted rangehood, which vents air to the outside, a recirculating rangehood consists of a fan with a charcoal filter that sucks up grease particles, heat, smells, and smoke, filters it, and then recirculates it back into the kitchen.
