Zephyr Ratings and Reviews

Our home smells great

Zephyr was easy to install and use. We set up schedules and let it do it’s thing. Now our home smells great all the time, which is amazing. With children and dogs, my home often looks like chaos. Thanks to Zephyr, it never smells that way.

100% natural

I’d read some things about other air fresheners maybe not being so healthy, so I was looking for something I could feel good about. The Zephyr essential oils are 100% natural, and that’s what my family deserves.

Customer Q&A


What is Zephyr?

Zephyr is new tech that diffuses essential oil right throughout your home through the vents. It’s controlled by an app so it’s easy to set up. Get rid of all of your different plug-ins (with different cartridges to remember to buy), scented candles, sprays, and candle warmers. Now your whole house will smell great, all the time, from one simple source.

Where do I get the scent cartridges?

You can order them right here from Sign up for our easy subscription service and they’ll automatically show up at your doorstep when you need them! You can also just order them whenever it’s time for more.

What does it smell like?

Our diffusers use our custom blends of 100% natural, therapy-grade essential oils, and we have a whole range of different options! Find one you like and stick with it, or enjoy our new pick for you every month. If you get one you don’t like, just send it back and you we will replace it for free–we’ll cover the shipping too! It’s all easy to set up from our website.

How do you hook it up

It’s super easy and you have a few options:-You can hook it up directly to a duct in your furnace room. To do that you just have to drill a small hole (we include the drill bit), affix a small grommet, and feed a small plastic tube into the hole. 
-If you don’t want to drill a hole, you can just jimmy the tube into the slot where your furnace filter goes, no problem!
-If you don’t want to mess with all of that, just find a return vent (one of the larger ones that sucks in air instead of blowing it out) and run the tube into that vent.

Wherever you decide to hook it up, it comes with a mounting strip on the back so it’s easy to affix to a vent or wall if you want to. The unit also needs power so you will have to find an outlet nearby to plug it in. From there you can configure it using your app.

Will it work at my place?

If your house is heated or cooled by air blowing out of vents, it will work! If you heat via baseboard heaters, radiant heat, and don’t have an air conditioner, it might not be the right fit.

The easiest way to know is, if you have a furnace or AC where you have to regularly change an air filter, it will work for you! Just hook it up where ever that air filter goes. You may need to run an extension cord to a power outlet if there isn’t one close to where your filter is.

I don't want to drill a hole. Will it still work for me?

Yes! You just have to feed a small tube into your duct where your air filter goes, or feed the tube into a return vent (one of the ones that sucks in air). Just find one in a discrete spot with an outlet nearby.

Will the scent oil damage my furnace or duct work?

Not at all! This technology is widely used in lots of commercial applications, like retail stores, hotel lobbies, and casinos. So you’ve likely experienced this product without realizing it. We have the benefit of years of use of this same product in those applications so we know it’s a stable technology that doesn’t have undesired side-effects on your equipment

Is it harmful to breathe the scent all the time?

Our scents are all made from 100% natural, therapy grade essential oil, so they’re total natural and safe to breathe. As with any household product, if you experience any possible allergy or negative effect, you should discontinue use, and we encourage pregnant or nursing women to follow advice from their physician on all household products. 

Also you can configure the timer so you’re only diffusing into the air intermittently.

Will it run all the time?

With our app you can set up windows of time when you want it to run. So you could set it up to run first thing in the morning for an hour or two, and then for a couple of hours when everyone gets home in the afternoon, then shut off at bedtime. This way you won’t waste your scent cartridge

I’m renting, will this still work?

As long as you have a furnace filter that you (or your landlord) change out periodically, it will work. You don’t have to alter the furnace or any of the equipment in the home. Just run the tube in where the furnace filter goes. If the air system is centralized among several apartments, or if you have no access to the furnace or air conditioner, it might not work for you. You should consult the landlord before installation.

How long will the scent cartridges last?

Everyone’s life is a little different, but we try to make one cartridge last 1 month. If your house is smaller you might use less, or if you run it all day you might use more. It just depends on how you set it up in your app. If you need cartridges more frequently or less frequently you can easily alter the schedule from our website.

Will drilling a hole in my vent, like, break something?

Nope! You just need to drill a small (7/16”) hole in the hollow vent right above your furnace. The included grommet creates an air-tight seal so you don’t have any leaks. If you change your mind, patching that hole is as simple as a small square of handy Duct Tape! (It is a duct after all!)

Can I hire someone to install this for me?

For sure! Any HVAC tech, electrician, or handyman should be able to install based on our instructions, and they can reach out to our support team with any questions.

What does the app do?

The app lets you set a schedule when the home diffuser will run, and at what level it will run, based on the needs of your life. So you can set it up at just the right level of potency, and set it up to run only when you want it to.

If the scent comes out of all of my vents, won't it be overpowering?

You can set it up to whatever level you want, right from your app. If you have company coming over, turn it up a little. If it’s too strong, turn it down–right from your smartphone or tablet.

In some seasons, my furnace and air conditioning don't come on very often. Will this still work?

You just have to run your fan every once in a while to keep the air moving. This is a good idea anyway, as it keeps the air fresh and clean and avoids warm or cool spots. You can turn it on or off directly from your thermostat. The most ideal thing to do is to set your fan to run automatically for 15-30 minutes per hour during the hours of the day you will be home. This is easy to do with most smart thermostats!
