You don't need to spend $200+ to get a safe, effective air fryer. Our testing found that several models under $100 deliver excellent cooking performance and strong safety scores. The key is knowing which budget models cut costs on marketing and packaging (fine) versus which ones cut costs on materials and safety testing (not fine). R3's value scoring weighs quality-to-price ratio, so a $50 air fryer with an 8/10 safety score ranks higher than a $50 model with a 5/10.
Even on a budget, don't compromise on safety. R3 recommends a minimum 7/10 safety score for any air fryer, regardless of price. Several models under $60 meet this threshold.
Budget air fryers typically offer 3-4 quart capacity (good for 1-3 people). If you need 5+ quarts for a larger family, expect to pay $70-100. Don't buy a too-small model just to save $15.
Budget models vary widely on warranty: some offer 1 year, others 2 years. A longer warranty on a budget product is a strong signal the manufacturer trusts their build quality.
Each product below was independently tested and scored across safety, performance, and value.
Each product has been tested, scored, and reviewed by our research team.
Each product is scored across 4 layers, weighted by importance to families.
We evaluated 4 countertop water filters currently in our database, scoring each across six dimensions: Safety (materials composition, certifications, regulatory compliance), Efficacy (performance, consistency, real-world results), Value (quality-to-price ratio), Usability (controls, cleaning, noise level), Durability (build quality, warranty, long-term reviews), Sustainability (environmental impact, materials sourcing).
For this budget list, we applied additional filters: - Maximum price of $100
Products that didn't meet these thresholds were moved to our "What We Didn't Pick" section with specific reasons.
0 products passed our budget filters and are ranked below by value score.
Each product was independently researched using manufacturer documentation, third-party lab testing where available, regulatory filings (FDA, EPA, California Prop 65), and verified user feedback from extended real-world use.
Best deals
Amazon Prime Day (July) and Black Friday (November) typically see 25-40% discounts on countertop water filters. Major brands like Ninja, Cosori, and Instant Pot participate in both events.
New model releases
Brands typically release new countertop water filters in Q1 (Jan-March) and ahead of holiday season (September). Previous-generation models drop in price when new ones launch.
Avoid full price
April-June and August are typically full-price months for countertop water filters. If you need one during these months, check manufacturer refurbished options for 20-30% savings.
R3 tip
Price drops do not change our safety scores. A discounted countertop water filter with a low safety score is still not recommended. Always check the R3 score before buying, regardless of the deal.
