Our Mission
We believe the products you bring into your home should support your health — not work against it. From water filters to cookware, air purifiers to supplements, we cut through the marketing noise and give you the information you need to make smarter buying decisions.
Temple Keep exists because the average person spends 90% of their time indoors, and the EPA has found indoor air and water quality can be 2-5x worse than outdoor levels. We're here to help you fix that — one product at a time.
Who We Are
Our team comes from backgrounds in health research, environmental science, and consumer product testing. We're based in the Northeast, where seasonal changes in air quality and water hardness give us a unique perspective on what works year-round.
How We Review Products
🔬 Our Review Process
Every product guide is built on a foundation of research, comparison, and honest assessment. Here's how we do it:
1. Research & Selection
We start by identifying the top products in each category using multiple sources: customer reviews, industry certifications, expert recommendations, and manufacturer specifications. We analyze 15-30 products per category before narrowing to our top 5-7 picks.
2. Criteria Development
For each category, we define the criteria that actually matter. For water filters, that's filtration capability, NSF certifications, flow rate, and filter lifespan. For air purifiers, it's CADR ratings, filter type, room size coverage, and noise levels. We publish these criteria so you know exactly what we're comparing.
3. Comparison & Testing
We compare products side-by-side against our criteria. When possible, we personally test products in real home environments. When we can't test every product, we're transparent about it — and we rely on verified customer data, third-party certifications, and extensive research to fill the gaps.
4. Honest Assessment
Every product we recommend gets a clear pros and cons list. We never hide the downsides. If a product has a flaw, we tell you. We also rate each product on a 1-10 scale so you can compare at a glance.
5. Ongoing Updates
We update our guides regularly — every 3-6 months — to reflect new products, price changes, and new research. Each guide shows its "last updated" date so you know it's current.
