Debbie R.
I have two dogs and I’d just gotten used to the smell. One Sirena by their beds, one in the lounge — no more panic-spraying before guests.
Isn’t this basically just a diffuser?
Not quite. Sirena combines continuous water circulation, room freshening, optional fragrance and a soft 7-color glow inside one compact unit. Instead of constantly reaching for another spray, you can leave Sirena set up in the rooms that tend to need freshening most.
How To Use Sirena
- Fill it — add fresh water to the bowl.
- Freshen it — add your preferred compatible fragrance or deodorizer, if you like.
- Twist it — switch Sirena on and let the circulating water freshen your space.
Specifications
Approx. 20.3 × 20.3 × 17.8 cm (about 8 × 8 × 7 in) and approx. 907 g (2 lb). Water-circulating design, 7-color LED illumination, compact tabletop footprint — made for bedrooms, living rooms, pet areas, offices and more.
What If I Don’t Love It?
Every Sirena is protected by our 30-Day Money-Back Guarantee + 3-Year Warranty. Put it in the room you’ve already been trying to keep fresh. If it isn’t for you, you’re covered.

Before you ask
Questions, answered.
Why do I get two for $29?
Because pet odor rarely stays politely in one corner. Our current offer gives you 2 PureMist Sirenas for $29 total. Keep one where odors normally start — like the litter area, dog bed or pet room — and put the second where everybody actually spends their time. Two rooms handled. One purchase.
How does the Buy 1 Get 1 Free work?
Claim the offer and you receive 2 PureMist Sirenas for $29 total. Not $29 each — $29 for both. Keep both, or put the second in the room you normally attack with air freshener every time somebody texts, “I’m five minutes away.”
What makes Sirena different from a giant air purifier?
Sirena focuses on easy everyday room freshening. You get circulating water, optional fragrance, compact placement and a soft 7-color glow without putting another huge appliance in the middle of your room.
Do I have to use fragrance?
No. You can use Sirena with water, or add a compatible fragrance or deodorizer when you want that extra fresh-room scent. You control how your room smells.
Where should I put the two units?
For pet homes, it’s simple: one where the smell starts and one where people gather. Think litter area + living room, dog bed + lounge, or pet room + bedroom. That’s exactly why we made the offer Buy 1 Get 1 Free.
Do I still need to clean my pet area?
Yes. Sirena works best alongside your normal fresh-home routine like washing pet bedding, cleaning litter areas and cleaning accidents at the source. Think of Sirena as the finishing touch that helps keep the room feeling fresh between cleans.
What if I don’t love it?
Put it in your actual home, around your actual pets, in the room you’re already trying to keep fresh. You’re protected by our 30-Day Money-Back Guarantee, plus every Sirena comes with a 3-Year Warranty.
When will my order ship?
Orders placed before 3pm ship the same day. Orders placed after 3pm ship the next business day. You’ll receive tracking as soon as your order is on the way.
