Grills are the vent coverings. Registers are the vents that supply air to rooms through slatted grills (with louvered dampers). Diffusers are a type of supply vent that provides 360&deg; airflow through a specialized grill (with damper). <\/strong> <\/p><\/div>\n\n\n<h2 class=\"wp-block-heading\">What Do They Have in Common?<\/h2>\n\n\n\n<p>The main commonalities of vents, grills, registers, and diffusers include facilitating the airflow of a home and being available in a wide variety of styles and colors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a Vent?<\/h2>\n\n\n\n<p>Vents refer to the holes, typically round, square, or rectangular, in your house that connect to ductwork. This could be ductwork that is part of your HVAC system, or it may be more localized, like the ductwork for your bathroom exhaust fan, range hood, or dryer. <\/p>\n\n\n\n<p>Please note that &lsquo;vent&rsquo; is commonly used as an umbrella term, and in some cases, it may be used to describe one of the other parts used as vent covers which this article will cover.<\/p>\n\n\n\n<p>Vents can either supply air to a room, remove air from a room, or release air outside. They are used for hot and cold air.<\/p>\n\n\n\n<p>The term is not associated with one function more than another. <\/p>\n\n\n\n<p>Vents can also be located in various places, depending on the purpose of the vent, which you can consider to be the type of vent. <\/p>\n\n\n\n<p>Supply vents are often found in the upper portions of a room. Return vents are commonly found in the lower portions of the room. <\/p>\n\n\n\n<p>Exhaust inlets can be on the ceiling, walls, and <a href=\"https:\/\/thetibble.com\/bathroom-fan-vented-down\/\" data-type=\"post\" data-id=\"3620\">occasionally the floor<\/a> (but this is uncommon). Then you have terminal vents, which lead to the outside (most often associated with localized exhaust systems). <\/p>\n\n\n\n<p>Depending on the type of vent, a backdraft damper may be required. <\/p>\n\n\n\n<p>Often, the actual covering of a vent is included in the term, but this is actually more accurately called the grill.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a Grill?<\/h2>\n\n\n\n<p>A grill is the covering of a vent. As they are used for almost all vents, they can be round, square, or rectangular. They also serve warmed, cooled, supplied, returned, and exhausted air, depending on the nature of the vent itself.<\/p>\n\n\n\n<p>The location of the grill obviously depends on the location of the vent, but anywhere there is a vent on the inside or outside of the house, you are likely to find a grill there too. <\/p>\n\n\n\n<p>The style of a grill ranges greatly and provides different looks as well as different functions. <\/p>\n\n\n\n<p>The most common style is a horizontally-slatted look, with either fixed or adjustable slats. But you can also get a large square mesh look. You can also get hooded slats. Then you can get all of these options for round vents as well. <\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"2000\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents.jpg\" alt=\"Illustrations of different types of grills for vents: non-adjustable horizontal slats, adjustable horizontal slats, large square mesh, hooded slats and round grill\" class=\"wp-image-22152\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-150x300.jpg 150w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-512x1024.jpg 512w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-768x1536.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-735x1470.jpg 735w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-168x335.jpg 168w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-174x347.jpg 174w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-260x520.jpg 260w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-320x640.jpg 320w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-384x768.jpg 384w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-480x960.jpg 480w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-540x1080.jpg 540w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"2000\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents.jpg.webp\" alt=\"Illustrations of different types of grills for vents: non-adjustable horizontal slats, adjustable horizontal slats, large square mesh, hooded slats and round grill\" class=\"wp-image-22152 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-150x300.jpg.webp 150w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-512x1024.jpg.webp 512w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-768x1536.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-735x1470.jpg.webp 735w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-168x335.jpg.webp 168w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-174x347.jpg.webp 174w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-260x520.jpg.webp 260w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-320x640.jpg.webp 320w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-384x768.jpg.webp 384w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-480x960.jpg.webp 480w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents-540x1080.jpg.webp 540w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/09\/Different-types-of-grills-for-vents.jpg\" id=\"mv-trellis-img-2\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>When there is the option to open and close a vent grill, it can be called a damper.

When we talk about registers, we are referring only to the vents that supply air into a room from the HVAC system. <\/p>\n\n\n\n<p>Registers are used for both heating and cooling. Since they work to supply air to a room, they are only found inside homes (there are no registers on your outside walls; these are different kinds of vents). <\/p>\n\n\n\n<p>In addition, since a register allows for the control of airflow, they come equipped with a damper. Typically, registers will come with a louver in terms of directionality.<\/p>\n\n\n\n<p>A damper is especially useful with a register, as it aids its function of controlling airflow. This feature allows the register to manipulate the amount of air coming in, and to a certain extent, the direction in which this air enters the room. Both of these influence the heating and cooling effect. <\/p>\n\n\n\n<p>You should note that <a href=\"https:\/\/thetibble.com\/air-vents-closed-unused-rooms\/\" data-type=\"post\" data-id=\"9999\">closing a register in an unused room<\/a> can have the opposite effect to what you are trying to achieve and it is not a practice recommended by any HVAC specialists that I have come across.<\/p>\n\n\n\n<p>As registers are just vents with grills and a specific purpose, all the various styles of grill are available to make the registers look good in whatever setting you place them. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a Diffuser?<\/h2>\n\n\n\n<p>A diffuser is another type of vent that supplies air into a room. The differences between diffusers and registers are the appearance and mechanism of action. <\/p>\n\n\n\n<p>While a register is typically square or rectangular (occasionally, it will be round), a diffuser is more likely to be round. It can also be square, but it&rsquo;s almost never rectangular. <\/p>\n\n\n\n<p class=\"has-text-align-center\">\n    <a data-amazonimages=\"\" target=\"_blank\" title=\"Accord ABCDWH08 Round Ceiling Diffuser, 8-Inch, White\" href=\"https:\/\/www.amazon.com\/dp\/B00196J3F2?tag=hvacbuzz-20\" rel=\"nofollow noopener\"><noscript><img decoding=\"async\" class=\"size-large aligncenter\" src=\"https:\/\/m.media-amazon.com\/images\/I\/41wOxMxa-HL._SL500_.jpg\" alt=\"Accord ABCDWH08 Round Ceiling Diffuser, 8-Inch, White\" title=\"Accord ABCDWH08 Round Ceiling Diffuser, 8-Inch, White\"><\/noscript><img decoding=\"async\" class=\"size-large aligncenter lazyload\" src=\"https:\/\/m.media-amazon.com\/images\/I\/41wOxMxa-HL._SL500_.jpg\" alt=\"Accord ABCDWH08 Round Ceiling Diffuser, 8-Inch, White\" title=\"Accord ABCDWH08 Round Ceiling Diffuser, 8-Inch, White\" data-mvt-skip=\"src\" loading=\"lazy\" data-trellis-processed=\"1\"><\/a>\n<\/p>\n\n\n\n<p class=\"has-text-align-center\">\n    <a data-amazonimages=\"\" target=\"_blank\" title=\"QUICK CONNECT HT-2X2-SPL6 Plastic Drop-In Supply Diffuser, 2' x 2' , White\" href=\"https:\/\/www.amazon.com\/dp\/B010PE0MA8?tag=hvacbuzz-20\" rel=\"nofollow noopener\"><noscript><img decoding=\"async\" class=\"size-large aligncenter\" src=\"https:\/\/m.media-amazon.com\/images\/I\/31Q9ZAVgrVL._SL500_.jpg\" alt=\"QUICK CONNECT HT-2X2-SPL6 Plastic Drop-In Supply Diffuser, 2' x 2' , White\" title=\"QUICK CONNECT HT-2X2-SPL6 Plastic Drop-In Supply Diffuser, 2' x 2' , White\"><\/noscript><img decoding=\"async\" class=\"size-large aligncenter lazyload\" src=\"https:\/\/m.media-amazon.com\/images\/I\/31Q9ZAVgrVL._SL500_.jpg\" alt=\"QUICK CONNECT HT-2X2-SPL6 Plastic Drop-In Supply Diffuser, 2' x 2' , White\" title=\"QUICK CONNECT HT-2X2-SPL6 Plastic Drop-In Supply Diffuser, 2' x 2' , White\" data-mvt-skip=\"src\" loading=\"lazy\" data-trellis-processed=\"1\"><\/a>\n<\/p>\n\n\n\n<p class=\"has-text-align-center\">      <\/p>\n\n\n\n<p>In addition, the diffuser will have a grill that helps the vent to provide 360&deg; airflow, as you can see from the below sketch. <\/p>\n\n\n\n<p>The greater control and ability to circulate air makes a diffuser a really good option in ceiling vents. There is no point in installing on the wall by the floor!<\/p>\n\n\n\n<p>You may have guessed due to their nature that diffusers are only used on the inside of a home. They are used in conjunction with both heating and cooling systems.<\/p>\n\n\n\n<p>To help give a diffuser its ability to control airflow, they are equipped with a damper.

This air is run through ducts to register or diffuser vents in specific rooms of the house. <\/p>\n\n\n\n<p>The air passes through the damper and grill into the room. <\/p>\n\n\n\n<p>Air, hot or cold, depending on the purpose of the running HVAC system, is then removed from the room through other vents, which are known as return vents. <\/p>\n\n\n\n<p>These are so called because they return the air to the HVAC system and they are also often covered with grills.  <\/p>\n\n\n\n<p>This air is then carried back to the heart of the HVAC system to be heated or cooled again. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sources<\/h2>\n\n\n\n<p><a href=\"https:\/\/ushomefilter.com\/supply-return-air-vents-difference\/#:~:text=Return%20Vents%3A%20These%20air%20vents%20suck%20air%20from,but%20depends%20upon%20the%20location%20of%20your%20ductwork.\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/ushomefilter.com\/supply-return-air-vents-difference\/#:~:text=Return%20Vents%3A%20These%20air%20vents%20suck%20air%20from,but%20depends%20upon%20the%20location%20of%20your%20ductwork.<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/www.neatceiling.com\/ceiling-diffusers-grilles-vents-differences-explained\/#:~:text=Vents%20differ%20from%20ceiling%20diffusers%20in%20that%20they,valuable%20purpose%20of%20covering%20up%20the%20duct%20opening.\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.neatceiling.com\/ceiling-diffusers-grilles-vents-differences-explained\/#:~:text=Vents%20differ%20from%20ceiling%20diffusers%20in%20that%20they,valuable%20purpose%20of%20covering%20up%20the%20duct%20opening.<\/a><\/p>\n\n\n\n<p><a rel=\"noreferrer noopener\" href=\"https:\/\/www.williamsonacrepair.com\/what-is-the-difference-between-air-vents-grills-and-registers\/#:~:text=A%20vent%20is%20the%20term%20used%20for%20all,system.%20All%20registers%2C%20grills%2C%20etc.%20are%20vent%20covers.\" target=\"_blank\">https:\/\/www.williamsonacrepair.com\/what-is-the-difference-between-air-vents-grills-and-registers\/#:~:text=A%20vent%20is%20the%20term%20used%20for%20all,system.%20All%20registers%2C%20grills%2C%20etc.%20are%20vent%20covers.<\/a><\/p>\n\n\n\n<p><a rel=\"noreferrer noopener\" href=\"https:\/\/aircondlounge.com\/types-of-grilles-in-hvac\/#:~:text=Linear%20bar%20grilles%20are%20almost%20always%20used%20as,grille%20has%20a%20maximum%20length%20of%20around%202500-2700mm.\" target=\"_blank\">https:\/\/aircondlounge.com\/types-of-grilles-in-hvac\/#:~:text=Linear%20bar%20grilles%20are%20almost%20always%20used%20as,grille%20has%20a%20maximum%20length%20of%20around%202500-2700mm.<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/www.engineermd.com\/2022\/07\/air-diffusers-in-hvac.html\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.engineermd.com\/2022\/07\/air-diffusers-in-hvac.html<\/a><\/p>\n\n\n\n<p><a rel=\"noreferrer noopener\" href=\"https:\/\/www.mtlfab.com\/index.php?pid=224&amp;aid=595&amp;pg=Ceiling+Diffuser+Damper\" target=\"_blank\">https:\/\/www.mtlfab.com\/index.php?pid=224&amp;aid=595&amp;pg=Ceiling+Diffuser+Damper<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/insights.jonite.com\/grilles-registers-and-diffusers-what-is-the-difference\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/insights.jonite.com\/grilles-registers-and-diffusers-what-is-the-difference<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>What Do They Have in Common?
