8 best air purifiers to combat wildfire smoke in Canada, according to professional ratings
As of Monday morning, Toronto's air quality was among the worst in the world, earning the highest rating — a 10+, Very High Risk — on the Air Quality Health Index.
On days with poor air quality, people are more likely to experience shortness of breath, difficulty breathing and coughing or wheezing — especially if they have a chronic respiratory disease like asthma or chronic obstructive pulmonary disease (COPD).
The small particles in wildfire smoke can get into your eyes and bloodstream, and if you have a heart or lung problem, you may experience problems earlier and at lower smoke levels.
According to Health Canada, using a portable air purifier that can filter fine particles is one way to protect your indoor environment from smoke pollution.
Air purifiers, also known as air cleaners, can improve indoor air quality by removing small contaminants that can harm your health.
According to the health authority, you should prioritize the following when choosing an air purifier:
Look for a device certified by the Association of Home Appliance Manufacturers (AHAM).
Choose an air purifier sized appropriately for the room you want to put it in.
Consider the clean air delivery rate (CADR) for the room size. The CADR describes how well the device reduces tobacco smoke, dust, pollen and wildfire smoke. To reduce fine particles, select a device with the highest CADR.
Choose an air purifier with a high-efficiency particulate air (HEPA) filter.
Avoid devices that produce ozone.
Not all air purifiers are made equal. Following Health Canada's recommendations, we've listed eight AHAM-certified air purifiers and included information about recommended room sizes and CADR ratings.

From Taboo To Tech: Fellow Health's $24M Raise Signals Big Shift In Men's Reproductive Health
Fellow Health just raised $24 million in a Series B funding round, bringing its cash haul across multiple offerings to $48 million. The San Leandro, California startup advances male reproductive health through "patient-centric testing solutions" and plans to use the capital infusion to expand its mail-in semen analysis services. Fellow Health provides clinical grade, mail-in analysis of male fertility and post-vasectomy status while committing to "privacy, convenience and timely results." Italready has a network of more than 2,500 fertility and urology providers nationwide and wants to "deepen its footprint" through expansion into employer-sponsored fertility benefits and "broader access initiatives." Don't Miss: The same firms that backed Uber, Venmo and eBay are investing in this pre-IPO company disrupting a $1.8T market — Accredited Investors: Grab Pre-IPO Shares of the AI Company Powering Hasbro, Sephora & MGM— led the latest funding round, in which asset management firm Forest Road participated for the first time. Forest Managing Partner of Life Sciences Bill Burkoth will join Fellow's board as part of the financing deal. Other investors since the initial round include Labcorp Venture Fund, Genoa Ventures and Mantis Venture Capital. "Fellow Health is exactly the kind of company we look for – operating in a large, overlooked market that's long overdue for disruption," Burkoth said in a statement. "With over 50,000 test results delivered so far this year, they've proven there is real demand for a better patient experience." Live sperm gets counted in fertility analysis. These cells can live three to days within the cervix, uterus and fallopian tubes, but usually die in under an hour outside a woman's body. The mail-in service addresses this time bomb with a "preservation solution designed to stabilize your sample and a gel pack that helps maintain a moderate temperature during transit." Mail-in post-vasectomy testing is less time critical because it counts both living and dead sperm. Trending: 'Scrolling To UBI' — Deloitte's #1 fastest-growing software company allows users to earn money on their phones. You can Fellow Health points to studies backing up its claim that it can provide "results on par with traditional one-hour semen analysis when analyzing samples received within 52 hours of when they were produced." It sells both testing products and a cryopreservation service without a doctor's prescription at its website. 'Male reproductive health should not be reactive or inaccessible,' Fellow CEO Brian Hogan said in the statement. 'We are on track to deliver over 40% year-over-year revenue growth, with a path to profitability in our fertility segment by 2026. This investment allows us to scale that vision and support both patients and providers with modern tools that work.'However, Fellow Health faces stiff competition in the male fertility space that could impact this optimistic revenue outlook. Rival Posterity Health booked $13 million in Series A funding earlier this year. The company partnered with Mark Cuban Cost Plus Drug Company in 2023 to provide access to treatments for infertility, sexual dysfunction and low testosterone. A year earlier, American telehealth provider Ro bought Dadi, another male fertility and sperm testing startup. Its reproduction preservation service for men looks like a direct competitor to Fellow Health's family of products. Ro has also made a splash in women's health, acquiring Modern Fertility in 2021.

Don't Just Sell Video Visits: Build a Healthtech Revenue Engine
What we learned at a high cost is that telehealth is not just about video visits, but about establishing a scalable revenue model. Opinions expressed by Entrepreneur contributors are their own. Before founding Bask Health, my brother and I once pitched a telehealth startup idea to a VC with a 40-slide deck and a "disrupt healthcare" tagline. He stared at us like we were pitching a smoothie truck. Turns out, nobody cares how "virtual" your care is if you can't explain your revenue model in under 30 seconds. That was a $22,000 lesson in developer costs, regulatory hurdles and hubris. So here's what we wish someone had told us on day one: you're not selling video calls, you're building a real business. In 2025, that means more than convenience. It means unit economics that hold up, multiple buyers beyond just patients and infrastructure that doesn't implode at scale. Below, we'll break down the four core revenue pillars in modern telehealth and how to stress-test each one before you burn through your seed round. Join top CEOs, founders and operators at the Level Up conference to unlock strategies for scaling your business, boosting revenue and building sustainable success. The Nut Graf Telehealth businesses built for 2025 and beyond can't survive on DTC visits alone. The ones that scale combine four revenue streams: Direct-to-Consumer, Employer, Payor and Ancillary, into a model that balances margin, compliance and demand. Here's how to structure yours and how to kill what isn't working, fast. 1. Don't just sell to patients: Land the employer account When we built our first virtual clinic, we assumed individuals would pay out of pocket for convenience. They did, but not in the volumes needed to cover CAC. The real ROI showed up when we signed our first self-insured employer. That one deal brought in 3x the monthly revenue of our entire DTC base. It was the clearest signal we'd seen: B2B revenue can subsidize your B2C growth. What works: Target companies struggling with chronic care costs or absenteeism.; Bundle care options: behavioral health, dermatology, menopause, etc.. Offer reporting dashboards and custom onboarding. Watch for: Stay HIPAA-compliant and FMLA-aware, especially if you're integrating with existing employer EAPs; Procurement cycles that take forever if you don't have a warm intro. Expect to hire B2B sales muscle early, or founder-led selling won't scale. Related: Healthtech Is the New Healthcare 2. Payor reimbursement is a slow game. Play it anyway We avoided insurance in the early days. Too slow. Too complex. But here's the truth: the payor model is hard to start and impossible to ignore. Yes, CMS still reimburses for telehealth, but the rules shift constantly. In 2025, audio-only visits are covered under limited conditions. Some CPT codes only apply to rural areas. And even if you're eligible, collecting payment is a marathon of prior auths and claim resubmissions. What works: Start small: pilot with Medicaid MCOs or carve-outs; Get surgical with your billing codes (RTM, CCM, POS-10, etc.); Hire someone who lives in your state's MAC guidance. Watch for: 60–90 day payment cycles (prepare your burn rate accordingly); Denials for bad documentation or misused modifiers; Overestimating what "covered by insurance" actually means. Related: Why Entrepreneurs Can't Rely on Traditional Retirement Plans (And What to Do Instead) 3. Ancillary services make or break unit economics We once sold $49 telehealth visits with a $120 CAC. It was cute until we looked at our bank account. We fixed it by integrating ancillary services, labs, pharmacy delivery, diagnostics, which turned $49 tickets into $149+. Patients don't want five apps. They want one seamless care journey. Bundling services increases LTV, improves outcomes, and gives you new margin layers to play with. What works: Partner with compounding pharmacies and lab networks. Use API-first infrastructure to automate fulfillment. Track where the drop-off happens between consultation and care. Watch for: State-specific lab-direct and prescribing laws; Ongoing logistics management (especially for shipping); Upfront build time, your developers will hate this unless you buy instead of build. 4. Stress-test your margins with this 4P matrix Before we launch any new care line, we run it through what we call the 4P Matrix: Category questions to ask Patient: Who pays? Individual, employer, or insurer? Payor: Which CPT codes or bundles apply? What's reimbursable? Partner: Are there labs, pharmacies, or vendors to integrate with? Peripherals: What are the add-ons? (RPM, async care, diagnostics?) If any one "P" is weak, you'll feel it in your burn rate within 60 days. If two are weak, you're bleeding cash. And if you can't tighten the loop within one quarter, sunset the service. Don't pitch telehealth. Pitch an economic engine. Investors don't want to hear about your "care journey." Employers don't care how empathetic your UI is. And patients? They want outcomes, fast. If you want to build a profitable telehealth company in 2025: Get clear on who pays and why. Design services that integrate seamlessly. Obsess over margin layers, not marketing buzzwords; And for the love of Wi-Fi, don't duct-tape your HIPAA compliance. Telehealth isn't a shortcut; it's infrastructure. But if you build it right, you're not just riding a trend. You're building healthcare's new backbone.
