The different base materials you'll find used in vents differ from one another primarily in appearance, but maintaining them is also something you should consider. Metals will be resistant to scratches, but may tarnish and need polishing semi-regularly. In areas with environments containing high salt content, such as beaches, iron-based vents may be prone to rust. Wooden vents won't require polishing, but if they're damaged they can be difficult to restore. Of course, for people interested in low-maintenance vents, there's always simple, cheap plastic or aluminum.

In terms of decorating atmosphere, a little thing like a vent can have a substantial impact. Less artistic vents will look either conservative and functional or simply merely cheap. Ones that have more craftsmanship invested in their designs will look better, but this shouldn't be confused with visibility. Both very plain and very beautiful vents can be highly visible, or not very visible at all, depending on how visually obtrusive the designs are.

The necessity of small spacing to protect the interior of the heating system from intrusion is sometimes neglected in models with more creative designs. It's best to not compromise this too much for the sake of good looks in a vent. If you do, you may soon find your oil filled radiator heater or other heating system damaged while you're admiring the vents!

Especially for floor heating vents which are in close proximity to unintentional harm, it pays to know how a pure vent contrasts with a finished vent. A vent may be finished to look like one thing when it's constructed almost entirely of something else. Many vents are labeled according to their finish, not their actual construction material, and those finishes may need to be cared for to keep looking lovely over the years.

A common but not quite universal inclusion with vents is a bundling with air filtering and damper box devices. With these, you can keep the air flow controlled at a level not provided by more basic vents. Most people consider it worth a little extra for the features, which are not yet found by default on all models.

It's difficult, but not impossible, for a vent to incorporate a lever control mechanism without hampering the product's visual flow. People who prize looks above all else will likely want to avoid models with levers for adjusting the ventilation blades. However, this feature does give the user more control over the vent's function, and so shouldn't be discarded out of hand before considering the benefits.

Vents the incorporate electronic features for automatically controlling their air flow are becoming more common and affordable. If you're interested in being able to easily channel heat into particular areas while closing other areas off, then these kinds of vents can be priceless in their convenience. And they don't even generally cost more than other vents, although you may have difficulty finding them in especially attractive designs.

With prices starting at a few dollars and going up to only about thirty or so, most people can afford to buy a vent now and then. The real cost is in bulk, however, since most buyers will need multiple vents and will want the vents to match. Buying from the same place will obviously be a wise choice, to benefit from bulk purchase discounts.
