Refurbished by Dyson's own experts and inspected, tested and renewed to Dyson standards, the Dyson Purifier Big+Quiet Formaldehyde BP04 is built to purify large spaces quietly. It projects purified air over 32 feet. A fully sealed HEPA H13-grade filter captures 99.97% of particles as small as 0.3 microns, including pollen, pet dander and smoke. A K-Carbon filter captures gases and odors, including nitrogen dioxide. A Selective Catalytic Oxidization filter continuously breaks down formaldehyde. Built-in sensors monitor air quality, including CO2 levels, and report it on the LCD screen. You can also control and monitor the purifier from anywhere with the MyDyson app.

Excellent Sound Bar, Official Packaging

Great product. It sounds amazing and came in what I think is new condition It came with all the Sonos official packaging and new cords. Verdi shipped through its Shopify store an hour after I placed the order. Many thanks, awesome product and shipper.

Couldn’t be happier! It was already charged when it showed up

Couldn’t be happier! It was already charged when it showed up, and I’ve been using it everyday for work. Definitely worth it!

Wow amazing!

Honestly, this is one of the best purchases I’ve made. The headphones are in perfect, like-new condition. If Verdi ever offers a product testing or review program, I would 100% want to participate. Thank you for offering this at a great price, and for the careful packaging and shipping.

Our daughter was very happy with the gift card. we have been pleased with things we have ordered in the past (refurbished coffee maker).
We like Verdi’s focus on sustainability. The card was easy to purchase and send.

Perfect - as new

Works great, I have never bought from Verdi but the quality is amazing.
Surpassed my expectations. I thought it would be a washed out refurbished product but this was almost as good as a new one. Just a tiny smug which came off easily. Very happy.

Meet Verdi. We find the best deals.

What does "certified refurbished" actually mean?

A refurbished product is one that was returned and then restored to as close to like-new as possible—including replacement parts and updated software where needed. Every refurbished product we sell is certified, meaning it's been restored by the manufacturer or an authorized partner and tested to original standards. Want the full breakdown? Read Refurbished, Renewed, Used… What's the Difference?

Are all refurbished items in equally good condition?

Yes. Every refurbished refurbished product is cleaned and tested to come as close to like-new as possible. We also carry new condition products which are unopened and brand new!

Do your products come with a warranty?

They do. Every refurbished product is backed by our 12-Month Refurb Warranty, and many new products carry longer coverage—1–2 years, and in some cases a Lifetime Warranty. Need specifics on your item? Contact us and we'll help.

Do you accept returns?

You can return most items within 30 days of delivery for a full refund. Items may be opened and inspected and still qualify, as long as they're returned in the same condition you received them and include all original accessories.

Do I have to pay for return shipping?
If the return is due to our error—such as an incorrect or defective item—we cover the return shipping cost.

When will I get my refund?
Refunds are typically issued within 5–14 business days after we receive your returned item.
