Using a Rainbow Vacuum as an Air Purifier - Comparison

Over the years we’ve serviced or sold thousands of Rainbow vacuums. As a result, we get asked certain questions quite a bit. One of these questions is about whether or not you can use a Rainbow vacuum as an air purifier. Today, Dustin talks about if you can and if you should!

Can You Use a Rainbow Vacuum as an Air Purifier?


Here we have three vacuums that represent just about all the different models of Rainbow vacuum out there. The SE on the left is similar to the D3 and D4. All three have 1 stage filtration – air comes in and is filtered through water. The E-series, in the middle, has added HEPA filtration for a total of two stages of filtration.  The 2-speed, on the right, is the same.

So, can you use these as air purifiers? The short answer is yes! Different models will have different efficiency, though. You will also need to take into consideration the sound the vacuum makes as it runs. Is it something you would really want to hear running for hours on end?

After listening to the sounds of the SE and E-series run you will notice how amazingly quiet the E2 2-speed is when you run it on air purifier mode! It’s a lot quieter, but doesn’t move as much air.

Should You Use a Rainbow Vacuum as an Air Purifier?

Okay, now that you know you CAN use your Rainbow vacuum as an air purifier you can ask the question “Should I?” What it boils down to is that a Rainbow is a $2000 vacuum cleaner. Why would you use a $2000 appliance to purify air when you can buy a dedicated air purifier that works way better for under $200?  There’s really no point in putting all of those hours of run time on a high-end appliance!

The price difference between the E-series 2-speed and a regular E2 (without the air purifier speed) is enough that you could buy yourself a good air purifier and have money left over.

Here Dustin has a couple air purifiers that we sell at They have up to 6 stages of filtration while the Rainbow vacuum only has 2. They also have a better fan and will do a better job of purifying your air. If you turn them on you’ll notice that they’re VERY quiet. Quieter than the Rainbow on air purifier mode, in fact! They will purify areas of up to 3,000 square feet! They have washable HEPA filters, they have ionization to help pull dust from the air, and they can remove odors.

To recap: Can you use a Rainbow vacuum to purify air? Yes. Should you? Probably not.
