Smoking weed indoors can be tricky, especially in dorm rooms or small apartments where smoke and odor tend to linger. A sploof solves this. A sploof is a personal filter that you exhale smoke through, so less smoke and odor reach the air around you. 

While DIY sploofs were once made with tubes and dryer sheets, today’s options use multi-layer filters, activated carbon, HEPA filtration, and improved airflow. Many come with replaceable cartridges.

This guide compares 9 popular sploofs on filter type, uses per filter, price, refill cost, and customer ratings.

What is the best sploof?

VEIL ranks #1 in our comparison. It’s the only one on this list with an aluminum body, and you replace only the multi-stage activated carbon cartridge, not the whole device. Many users get up to a month of heavy use from one cartridge. 

That works out to about $13 a month if you buy the 3-pack. If you only smoke now and then, a cheaper sealed model like Smoke Buddy will do until its filter wears out.

9 Best Sploofs: Filters, Refill Costs & Ratings Compared

1. VEIL: Reusable Carbon Sploof for Vape

VEIL is a reusable sploof with a replaceable multi-stage cartridge built around activated carbon filtration media. A one-way airflow system sends your exhale through the cartridge and out a wide-flow exhaust grate, which reduces visible vapor and the odor that comes with it. The aluminum alloy body is made to last, so the cartridge is the only part you keep buying.

Key features include:

• Replaceable multi-stage activated carbon cartridge
• Aluminum alloy body
• Food-grade silicone mouthpiece
• One-way airflow system
• Wide-flow exhaust grate for easier exhalation
• No batteries or charging required

Unlike disposable sploofs, VEIL lets you swap the cartridge instead of buying a whole new device. It costs $34.99 and comes with replacement cartridges worth $19.99 each and $39.99 for a three-pack.

Pros: Aluminum body, refillable carbon cartridge, no batteries.

How Does a Sploof Work?

A sploof works like a mask for your exhale. When you breathe smoke into it, the smoke passes through filters that catch the smell and the visible smoke before the air comes out the other end.

Most sploofs use one or both of these filters:

• Activated carbon removes the smell. It’s packed with tiny pores that trap odor molecules, including terpenes (the compounds that give weed its scent).
• HEPA filters remove the visible smoke. They catch tiny particles, and a true HEPA filter traps 99.97% of particles as small as 0.3 microns.

Some sploofs also protect their filters from moisture, which helps them last longer. Smoke Eraser Pro uses a removable prefilter to catch moisture and resin. Smoke Trap+ uses a water-repelling screen to keep its HEPA filter dry.

Frequently Asked Questions About Personal Smoke Filter

Do sploofs actually work?
Yes, a good sploof filters most of the visible smoke and greatly reduces the smell, but how well it works depends on the type of filter and how fresh it is.

How long does a sploof last?
Most sploofs last 150 to 500 exhales per filter, and many VEIL users get up to a month of heavy use from one cartridge.

Does a sploof work for vapes?
Yes, a sploof filters vape clouds too, but thick vapor adds moisture, so let the filter air-dry after heavy sessions to keep it working longer.

Can a sploof hide the smell completely?
Yes. A sploof hides most of the smell by filtering your exhale before it reaches the room. It works best with an open window or a fan.

Are dryer-sheet sploofs worth it?
Not really, because a dryer-sheet sploof mostly covers the smell with fragrance and clogs quickly, while activated carbon actually traps odor molecules.

Final Thoughts: Which Sploof Should You Choose?

It comes down to how often you smoke and where you’ll use it. Here’s the quick version:

• Lowest cost: vonSploof. It’s $19.88 upfront, and refills work out to about 2 cents per use.
• Heavy daily use: Smoke Eraser Pro. The removable prefilter and optional Docking Station keep the HEPA filter dry. Smoke Trap+ is a close second, with its 4-stage filter rated for 500+ puffs.
• Most portable: Smoke Buddy Junior. It weighs 2.4 ounces and has the lowest upfront price at $19.95.
• Eco-friendly pick: PHREND. Its plant-based filter is made to break down in under three years.
• Durable build with multi-layer filtration: VEIL. It has an aluminum body, and you replace only the cartridge.
• Cheap refills: Sploofy Pro II. Cartridges cost $14.99 each.

Sploofs in modern times have come a long way from those DIY versions made using a tube and some dryer sheets. There are now smaller everyday options, reusable models, and filters that can be replaced instead of throwing the whole device away.

Options like Smoke Buddy, Sploofy, vonSploof, Smoke Eraser, and VEIL each take a slightly different approach to size, filtration, and maintenance. The frequency of your sploof usage, where you plan to carry your sploof, and how much you can maintain are all factors that might help in deciding.
