Quick Answer: Fill power measures how much space one ounce of down occupies in cubic inches. A 600 fill power pillow is good quality, 700+ is premium, and 800+ is luxury-grade. Canadian Hutterite goose down is among the finest in the world due to our cold climate. Expect to pay $100 to $350 for a quality Canadian down pillow, with our Highland Feather range starting at $206.

What Fill Power Actually Means
Fill power is the single most important number on a down pillow, and most people have no idea what it means. Here is the plain version.
Take one ounce of down clusters and put them in a graduated cylinder. The number of cubic inches that ounce fills is the fill power. A 600 fill power down occupies 600 cubic inches per ounce. An 800 fill power down fills 800 cubic inches per ounce.
Higher fill power means larger, more mature down clusters that trap more air. More trapped air means better insulation and more loft with less weight. An 800 fill power pillow feels light and airy compared to a 600 fill power pillow of the same size, because it needs fewer ounces of down to achieve the same loft.
Why Canadian Down Ranks So Highly
Canada's harsh winters force waterfowl to grow denser, more resilient down clusters for insulation. Hutterite goose down, farmed in Alberta, routinely achieves 750 to 850+ fill power. This is comparable to the best Hungarian and Polish goose down, and the cold-climate advantage gives Canadian down a natural edge in cluster size and durability. The Canadian Down & Feather Company and Highland Feather both source domestically.
One common misconception: fill power does not indicate firmness. A high fill power pillow is not automatically firm. Fill power measures the quality of the down. The firmness comes from how much down is stuffed into the pillow. A 700 fill power pillow packed tightly with 30 ounces of down will be firm. The same fill power with 18 ounces will be soft. This is why good down pillow manufacturers offer the same fill power in soft, medium, and firm densities.
Down vs Feather: The Difference That Matters
Down and feather come from the same bird, but they are structurally different, and that difference changes how your pillow sleeps.
Down Clusters
Down is the soft, three-dimensional plumule found under the outer feathers, closest to the bird's body. Each cluster looks like a tiny dandelion puff with filaments radiating from a central point. These filaments trap air, which provides insulation and loft. Down clusters have no quill, so they compress smoothly without poking through the pillow shell.
Feathers
Feathers have a flat, two-dimensional structure with a central quill (shaft). They provide more structure and support than down but less loft and insulation. Feathers are heavier per unit volume, and the quills can sometimes poke through a pillow shell if the thread count is low.
Blends
Most affordable "down pillows" are actually blends. A pillow labelled "75/25" contains 75% down clusters and 25% feathers. The feathers add structure and support, while the down provides softness and loft. Common ratios you will see in Canada:
| Ratio | Feel | Price Range (CAD) | Best For |
|---|---|---|---|
| 100% down | Very soft, maximum loft | $200 to $400+ | Luxury, back sleepers who want cloud-like softness |
| 90/10 (down/feather) | Soft with slight support | $150 to $300 | Most sleepers, good all-around choice |
| 75/25 | Medium, balanced | $100 to $200 | Side sleepers who need a bit more structure |
| 50/50 | Firmer, more support | $60 to $120 | Budget option, stomach sleepers |
| 100% feather | Firm, flat with quill poke risk | $30 to $60 | Decorative pillows, couch cushions |
Brad, Owner, 40+ years of experience: "I tell customers to think of the ratio like coffee. 100% down is a pure single-origin pour-over. A 75/25 blend is a very good drip coffee. Both are real coffee, both taste great, but the pure stuff costs more. Below 50/50, honestly, you are just sleeping on feathers with some down mixed in."
Fill Power Ranges and What You Get
Not all down is equal. Here is what each fill power range gets you and what you should expect to pay in Canada.
400 to 550 Fill Power (Entry Level)
Typically duck down rather than goose. These pillows are heavier for the same loft, compress faster over time, and need replacing sooner. Still a genuine down pillow, but not the kind you tell your friends about. Found at department stores and big-box retailers for $40 to $80.
600 to 650 Fill Power (Good Quality)
The sweet spot for most Canadians. Usually white goose down with good cluster size. Lighter than entry-level down, better loft retention, and a noticeable improvement in sleep quality. Our Miracle Sleep Pillow ($209) sits in this range, and it is one of our most consistently recommended pillows. The Lisburn 600 Loft Pillow ($206) from Highland Feather is another strong option at this level.
700 to 750 Fill Power (Premium)
This is where Canadian Hutterite goose down really shines. The clusters are larger, the loft is noticeably higher, and the pillow feels like sleeping on a controlled cloud. These pillows retain their loft for years with proper care. Our Carmel 725 Loft Hutterite Pillow ($348) and the Iceland 725 Loft Pillow ($340) from Highland Feather represent this tier well.
800+ Fill Power (Luxury)
The highest grade, using only the largest, most mature goose down clusters. Our Mostar 750 Loft Hungarian Goose Down Pillow ($334) approaches this territory. At this level, the down is extraordinarily light, almost weightless in your hands, and the loft is remarkable. These pillows can last 10 to 15 years with proper washing and care. They are an investment, not a purchase.
Fill Power Is Not Everything
A 600 fill power pillow with the right amount of fill for your sleep position will outperform an 800 fill power pillow with the wrong amount. If you are a side sleeper, you need more fill (firmer density) regardless of fill power. If you are a back sleeper, you need less fill for that gentle cradle. The fill power determines quality. The fill weight determines firmness.
Down Pillow Allergy Myths vs Reality
This is the section most people need to read, because there is a lot of outdated information floating around.
Myth: Down Pillows Are Bad for Allergies
This was more true decades ago. Modern down processing involves multiple wash cycles at high temperatures, which removes dust, dander, and allergens from the down clusters. A properly processed, high-quality down pillow with a tight-weave shell (300+ thread count) is actually one of the most hypoallergenic pillow options available.
Here is the counterintuitive part: synthetic polyester pillows often harbour more dust mites than down pillows. Down's tight cluster structure and the high thread count shells used to contain it create a barrier that dust mites struggle to penetrate. A 2013 study in the Journal of Allergy and Clinical Immunology found that well-maintained down bedding did not increase allergen exposure compared to synthetic alternatives.
When Down Allergies Are Real
True down allergies exist, but they are less common than most people think. What most people react to is not the down itself but dust mites that accumulate in any pillow over time, or the residual dust and dander left by poor processing. If you have been told you are "allergic to down," consider these possibilities:
- You may be reacting to dust mites, not down. A pillow protector solves this regardless of fill type.
- You may have used a cheap, poorly processed down pillow. Quality matters enormously.
- You may have a genuine feather allergy (more common than down allergy). Try a 100% down pillow without feathers.
If you have a confirmed allergy to waterfowl proteins, down is genuinely not for you, and that is fine. Our Natura Organic Latex Pillow ($196) and Lavender Memory Foam Pillow ($45) are excellent alternatives. No judgement either way.
Testing in Person in Brantford
If you are unsure whether you react to down, visit our showroom on West Street and spend a few minutes with one of our down pillows. Dorothy, our sleep specialist, can walk you through the differences between our Highland Feather down pillows and our latex and foam options. Sometimes the best allergy test is five minutes in-store rather than a hundred-dollar gamble online.
RDS Certification and Ethical Sourcing
Where your down comes from matters. The Responsible Down Standard (RDS) is the most recognized certification for ethically sourced down, and it addresses the legitimate concerns people have about animal welfare in the down industry.
What RDS Guarantees
RDS certification, administered by Textile Exchange, ensures that:
- No live plucking or molt harvesting occurred
- Birds were not force-fed (ruling out foie gras by-product down)
- Animals had access to water, food, shelter, and veterinary care
- The entire supply chain, from farm to finished product, is audited and traceable
A product can only carry the RDS label if 100% of its down content is RDS certified. There is no "partial" RDS certification.
Canadian RDS-Certified Manufacturers
Several Canadian companies carry full RDS certification:
- Canadian Down & Feather Company (Toronto): all products RDS certified, made in Canada
- Highland Feather (which we carry at Mattress Miracle): sources ethically harvested Hutterite and Hungarian goose down
- Naturepedic: RDS certified, also carries GOTS organic certification
Beyond RDS
Other certifications to look for on down products sold in Canada:
Certifications Worth Checking
- OEKO-TEX Standard 100: Tests for harmful chemicals in the finished product
- Downpass: European animal welfare standard, similar to RDS
- Global Traceable Down Standard (TDS): NSF International's traceability standard
- Bluesign: Environmental sustainability certification covering the entire supply chain
Who Should Consider Alternatives
Down is not the right fill for everyone, and we would rather be honest about that than sell you something that will not work.
Hot sleepers: Down is an insulator. That is what it is designed to do. While breathable, down traps warmth more than latex or buckwheat hulls. If you wake up sweating, consider a cooling gel pillow or a latex pillow instead.
Stomach sleepers: Down pillows, especially high-fill-power ones, tend to be too lofty for stomach sleeping. You need a very thin, flat pillow or no pillow at all. Our guide on sleeping without a pillow covers this in detail.
People who want zero maintenance: Down pillows need regular fluffing, occasional washing, and proper drying. If you want a pillow you can ignore for years, a memory foam or latex option is more practical.
Confirmed waterfowl allergy sufferers: As discussed above, if you have a verified allergy to waterfowl proteins (not just dust mites), down is off the table.
How to Wash and Care for Down Pillows
Proper care is the difference between a down pillow that lasts 3 years and one that lasts 15. Most people either over-wash or under-wash their down pillows. Here is the right balance.
Washing Frequency
Wash your down pillow 2 to 3 times per year. Use a pillowcase and a pillow protector between washes. The protector catches sweat, oils, and skin cells before they reach the down, keeping the clusters clean and lofted longer.
How to Wash
Use a front-loading washing machine (top-loaders with an agitator can damage the clusters). Wash on a gentle cycle with warm water and a small amount of mild detergent. No bleach, no fabric softener. Fabric softener coats the down filaments and reduces their ability to trap air, which kills loft.
Run an extra rinse cycle. Soap residue left in down clusters causes clumping and odour.
Drying (This Is Where People Go Wrong)
Tumble dry on low heat. This takes a long time, sometimes 2 to 3 hours for a large pillow. Add 2 to 3 clean tennis balls or dryer balls to break up clumps as the pillow dries. Check every 30 minutes and manually fluff.
The pillow must be completely dry before you put it back on your bed. Down that is even slightly damp will develop mildew and a musty smell. When you think it is dry, give it another 20 minutes.
The Smell Test
After drying, press the pillow to your face and breathe in. If it smells clean and neutral, you are good. If it has any musty or damp smell, put it back in the dryer. Down that smells off is down that is not fully dry, and sleeping on it will make the problem worse.
Daily Maintenance
Give your down pillow a good fluff every morning. Grab both ends and push them together a few times, then shake it. This redistributes the clusters and restores loft. It takes ten seconds and genuinely extends the pillow's life.

Dorothy, Sleep Specialist: "If you have never slept on a 700+ fill power down pillow, the Mostar or Iceland will be a revelation. There is a noticeable difference in how light it feels compared to a 600 fill power pillow. I describe it as the difference between a good hotel pillow and a great one."
For customers who love the feel of down but want something at a lower price point, our Aqualite II Synthetic Silk Pillow ($50) mimics the soft drape of down without the premium price tag. It is fully machine washable, which is a real advantage for people who prefer low-maintenance bedding.
Frequently Asked Questions
Is goose down better than duck down?
Generally yes. Geese are larger birds with bigger down clusters, which translates to higher fill power. Duck down typically maxes out around 600 to 650 fill power, while goose down can reach 800+. For fill powers under 600, you may not notice a significant difference. Above 600, goose down is measurably superior in loft and durability.
How long do Canadian down pillows last?
With proper care (regular fluffing, washing 2-3 times per year, using a pillow protector), a quality 600+ fill power down pillow lasts 5 to 10 years. Premium 700+ fill power pillows can last 10 to 15 years. Compare that to synthetic pillows, which typically need replacing every 1 to 3 years.
Can I try a down pillow at Mattress Miracle before buying?
Absolutely. We keep our full Highland Feather range in the Brantford showroom, and you can feel the difference between a 600 and a 725 fill power pillow in person. Call Talia at (519) 770-0001 to confirm stock before your visit.
What thread count should the pillow shell be?
For down pillows, the shell thread count matters more than most people think. Below 300 thread count, down clusters and especially feather quills can poke through the fabric. Look for 300 to 500 thread count for good containment. Our Carmel 725 uses a 700 thread count shell, which is overkill in the best possible way.
Are down pillows worth the price compared to memory foam?
They serve different purposes. Down pillows are soft, moldable, breathable, and compress to nearly nothing when you fold them. Memory foam pillows hold a fixed shape, provide consistent support, and do not need fluffing. If you want that traditional, hotel-luxury cloud feel, nothing replicates genuine down. If you want cervical support that stays in place all night, foam is better. Many of our customers own both and rotate based on preference.
